Zero Configuration Email Delivery for Cloud-Hosted Customers

Zero Configuration Email Delivery

The ability to send email is essential for any booking system.

From booking confirmations and reminders, to invoices, notifications, and password resets, booking and scheduling systems rely on email.

MIDAS naturally supports the sending of email, but we’ve made some exciting and significant improvements to email sending for our cloud-hosted customers for v4.42.

But first, let’s look at the existing ways in which MIDAS can send email.

Until now, the sending of email by MIDAS has been through a choice between “Sendmail” or “SMTP”.

What is Sendmail?

Available on Linux-based servers, Sendmail is a built-in server application for sending email directly from the server itself. Read more about Sendmail.

What is SMTP?

SMTP (or Simple Mail Transfer Protocol) is the standard language used by computers to send emails across the internet. Read more about SMTP.

Sendmail vs SMTP

Both Sendmail and SMTP options have been available in both our cloud-hosted and self-hosted editions.

“Sendmail” has long been the default ‘out of the box’ email transport setting for cloud-hosted customers. However, we’ve always encouraged customers to move over to SMTP as soon as possible.

That’s because generally email deliverability rates are substantially higher when MIDAS is configured to send email through a customer’s own SMTP server, than if instead sent directly through our own servers.

Whilst Sendmail is configured to work ‘out of the box’ for cloud-hosted customers, SMTP requires a little more configuration.

To configure MIDAS to send email via SMTP, you will need:

  • The address of your SMTP server
  • The correct port number
  • The SMTP username and password
  • The correct SSL, TLS, or STARTTLS encryption method setting

You will also need to ensure that your SMTP server accepts connections from your cloud-hosted MIDAS system. In addition, your organization’s domain must be configured to allow MIDAS to send email on behalf of your domain.

This requires significant configuration and setup. We want to simplify this for our cloud-hosted customers. That’s why we’re introducing cloud email sending.

Introducing “Cloud Sending”

New Zero Configuration Email Sending Option
New Zero Configuration Email Sending Option

For MIDAS v4.42, we’ve introduced a new “Cloud” option for sending email. This new option is available to all cloud-hosted customers, and replaces the previous “Sendmail” option. (Sendmail continues to remain an option for self-hosted customers).

With the new cloud email option selected, you won’t need to specify an SMTP host, or enter credentials or specify ports – MIDAS will take care of all of that!

We have partnered with a dedicated transactional email provider specializing in high-deliverability email delivery services, to provide efficient and reliable email delivery for cloud-hosted customers who select the “Cloud” email sending option.

Zero Configuration Email Sending

To complement our new “cloud” email offering, we’ve also included a “Zero Configuration” option.

With this option enabled, MIDAS and Mailgun will seamlessly handle email delivery for your MIDAS system. You won’t need to configure an outgoing email address, nor will you need to update your organization’s domain’s SPF (Sender Policy Framework) DNS record – email will just ‘work’ right out of the box.

Of course, if you wish to customize the “send from” or “reply to” addresses, you can untick the “Zero Configuration” option and change those settings.

But in its simplest form, our new “cloud” email sending and “Zero Configuration” options mean that brand new cloud-hosted email systems can now reliably send email right from the outset.

Migrating from Sendmail to Cloud email sending

For our existing cloud-hosted customers, if you’re currently using the “Sendmail” option in your MIDAS system, you’ll be automatically migrated to “cloud” sending soon after we update you to v4.42.

If you do not wish to use the new “Cloud” sending option, you should update your MIDAS settings to instead send email via SMTP.

You can change your MIDAS email settings via MIDAS Admin Options → Manage MIDAS → Email.

If your cloud-hosted MIDAS system is currently configured to send email via SMTP, this setting will be unaffected when we update your booking system to v4.42. Of course, you can then always change over to use the cloud email sending option at any time.


MIDAS v4.42 introduces a new advanced print option that allows bookings to be printed for specific days of the week within a selected date range.

The “Print” icon in the MIDAS toolbar allows for quick printing of bookings shown in the current booking grid.

Right-clicking (or long-pressing on touch devices) this icon opens an advanced print dialog.

From this dialog, you can customize the booking printout in a number of ways:

  • Change the layout
  • Set the date range
  • Restrict to certain times
  • Restrict to certain rooms
  • Restrict to certain booking types
  • Filter bookings based on advanced criteria

We’ve improved the date range customization section in MIDAS v4.42 to now also allow selection of specific days of the week across the selected date range.

Previously, selecting a date range would simply include bookings for each and every day in the range. Now you can limit this to only include bookings on certain days of the week.

For instance, if you’re only interested in printing bookings that take place on Saturdays and Sundays over the next three months, you can now do so.

This makes it easier to generate focused and concise booking printouts without unnecessary information.


MIDAS 2025 Year in Review: Product Updates, Features, and Improvements

2025 marked 20 years since work first began on the concept of our MIDAS booking system, with the very first version “0.01” coming into existence on 10th December 2005.

None of those very early 0.xx versions were ever made public and were instead used to test and refine the functionality of the software and to fix bugs.

The first “public” release, v1.00, came just a few months later in early 2006, which means that 2026 will mark MIDAS’ “official” 20th anniversary.

Our software certainly has longevity and a proven track record, and two decades later remains in active development. We regularly release booking software updates with new and improved features, and in this post we thought we’d summarize some of the highlights over the past 12 months.

💬 Unrivalled Customer Support

As well as the peace of mind our longevity gives to users, we know that customers also care about good customer service. This is just one of the areas that our customers regularly praise us for.

At the start of the year, we reviewed how responsive our support service had been over the previous 12 months, and you can read our customer support performance review.

♻️ Reduced Environmental Impact

Given our high levels of service, we clearly care about our customers. But we also care about the environment too.

As with any online or cloud-based business, computer and server equipment runs on electricity.

The Website Carbon Calculator is an innovative initiative which analyzes five key metrics to estimate the carbon emissions of any website.

Back in 2021 we were “greener” than 86% of all websites globally.

By 2025, we are now greener than 91% of all websites, and have reduced our carbon footprint by 5% over that period.

🇺🇸 US Tariffs

In April 2025, US President Donald Trump announced he would be imposing new ‘Tariffs’ on the majority of countries in the world, including the UK (where we’re based).

Concerned US customers were reaching out to ask whether the cost of MIDAS was affected by these tariffs. The good news was that tariffs only applied to physical or tangible goods – they didn’t apply to “services”, and therefore our prices for US customers were unaffected.

Politics aside, here’s what else happened in MIDAS in 2025…

⏱️ Staying “Signed In”

In April 2025, MIDAS v4.29 introduced a brand new “Stay signed in” option that truly allowed users to remain signed in between sessions. This was a game-changer for many who were frustrated at having to sign-in each time they opened their browser.

Of course remaining signed-in was something that could already be achieved with Single Sign-In (SSO) support via Active Directory – something MIDAS has supported for some time.

🔐 Improved Single Sign-On (SSO) support

In August 2025, for v4.40, we improved Single Sign-On support by expanding support to include SAML 2.0 Identity Providers.

🚪 Venues, Rooms, Spaces, and more

When we first came up with the concept of MIDAS two decades ago, we needed a term to refer to the “spaces” being booked. If you don’t know, MIDAS was originally written for a school environment, and we didn’t want to use “room” for facilities like sports halls or dance studios. We settled on the generic term “venue” to refer to a “bookable space” within the software, and this terminology has been in use ever since.

However, this year we introduced a brand new setting to replace the term ‘venue’ with something more applicable to what each organization uses MIDAS for. So if you’re a bowling alley, you can change the term to “lane”. Or if you’re running a complex of recording studios, you can change venue to “studio”.

🧾 Invoice Improvements

Invoicing is arguably the one area in MIDAS that receives the most user suggestions for new and improved features. That’s certainly not to say that the extensive invoicing capabilities of MIDAS aren’t good enough – it’s simply that every organization invoices differently – there’s no “standard that everyone uses”. That’s even more true as we have customers in dozens of countries around the world, and accounting/audit rules differ between jurisdictions.

Our most recent improvement to invoicing in 2025 was to support setting tax rates to three decimal places. Now, in most places in the world, tax rates are given to two decimal places, but there are actually a few exceptions!

Here are some examples:

  • Washington (United States):
    Washington law allows certain local sales/use tax rate increases in 0.001% increments
  • California (United States):
    California’s district sales taxes commonly use 0.125% increments. 
  • New York City (United States):
    8.875% is the combined sales tax rate in New York City. It comprises 4.00% (New York State sales tax), 4.50% (New York City sales tax), and 0.375% (Metropolitan Commuter Transportation District (MCTD) surcharge).

Allowing for tax rates to be specified to three decimal places, ensures MIDAS can accurately support regional and local tax rules across different jurisdictions.

This year, we also made invoices searchable and allowed the order of invoice items to be changed. Plus we provided greater control over unsent invoices by allowing an administrator to specify a date each month when unsent invoices are automatically sent to customers. This improvement better accommodates organizations that typically invoice on a specific date every month.

⬇️ Import Improvements

The ability to import data into a MIDAS resource scheduling system is crucial. Many customers who make the switch to MIDAS naturally wish to import data from their previous venue booking system.

The import tool in MIDAS allows for this. However, every booking software application is different – there’s no standardized format for how an application chooses to store and present data.

So our import tool strives to accommodate as many different data formats and “peculiarities” as possible for maximum compatibility when migrating from other booking systems.

In 2025, we introduced support for importing ‘dynamic’ .csv files. Traditionally, a Comma Separated Values (or CSV file) contains “one record per line”.

Some booking systems export to .csv files in a non-standard way, where data may actually be split across multiple lines. MIDAS can now support importing such files.

MIDAS also now supports importing multi-venue bookings. Traditionally, each record or “row” in a CSV file containing bookings should equate to a single booking (i.e. one row = one booking). However, some booking systems, such as Skedda, export multi-room bookings (where a booking takes place across multiple bookable spaces) as single records.

When importing such data into MIDAS, the software can now correctly identify and process such records.

📋 Logging and Audit Improvements

Every MIDAS booking system includes a “Recent Activity” log. In this audit log, every user action which takes place in the booking system is timestamped and logged. This allows administrators to keep track of all activity occurring within the system.

We’ve made a number of improvements in this area in 2025, including:

  • The Recent Activity log now differentiates between custom booking and client fields
  • The Recent Activity log now differentiates between removed obsolete and unsent invoices
  • Changing MIDAS core settings is now recorded to the Recent Activity Log
  • Dynamically duplicated or moved bookings are more clearly identified in the Recent Activity log

👩‍💼New User Permissions

Audit logging is certainly very useful – but we also provide administrators the ability to set an extensive range of permissions to individual user accounts. In 2025, we’ve added two additional new user permissions:

📲 User interface improvements

The user interface – or UI – of MIDAS has evolved considerably since 2005. This has been driven by advancements in new web technologies, browsers, and style trends. At the same time, we also know that functionality and familiarity are also key drivers for our users.

We’ve made a number of UI improvements to MIDAS this year, including;

♿️ Accessibility Improvements

Accessibility on web pages and web apps simply wasn’t a “thing” back in 2005 when MIDAS was born. Today, it’s not only important, it’s an essential consideration for many.

We first built in keyboard shortcuts to MIDAS well over a decade ago, and not long after introduced a special “high-contrast” visual theme too. Since then newer technologies and accessible web standards have emerged, and we continually strive to make MIDAS more accessible with every update.

This year, we’ve made a number of tweaks including better contrast for text on the booking availability grid display on public booking/request screens. We’ve also revamped the included help documentation for our most recent update, v4.41, to make it more accessible.

✅ Optimizations

Whilst many of the changes we introduce with each new version are visible, many take place behind the scenes.

We frequently review the code that makes up our software, and we’re always looking for ways to make it more efficient and run faster. A couple of years ago we experimented with using AI to assist with code optimization, and the results were impressive.

We continue to use AI to assist with this task this year to realize some small performance optimizations Rest assured, we certainly don’t let AI loose on the source code, and a human review of all AI generated code optimizations is carried out before the changes are accepted.

In addition to code optimization, we also look at database query optimization. These are the “commands” that MIDAS sends to the backend storage database, and the data it receives back in response. Communication with the database is actually one of the biggest factors that can affect performance, and so any gains in this area are always welcome.

We’ve made a number of optimizations to both code and database queries in 2025 to further improve performance and responsiveness of our software.

➕ New Add-ons

This year saw the introduction of two exciting new optional “add-ons” for MIDAS, allowing you to;

🔎 Looking ahead to 2026

As we mentioned at the top of this article, MIDAS officially celebrates its 20th anniversary in 2026, so watch this space for exciting updates in the coming months…


User Interface improvements in v4.41

Whilst we love adding new and improved features in every software update, we also know that user interface (UI) and user experience (UX) are important too!

We’ve made a number of UI/UX improvements for our latest update. Some of these will be immediately noticeable, others are more subtle.

In this post, we’ll highlight some of the UI and UX improvements in MIDAS v4.41.

A more concise user bar

If you’ve been using MIDAS for a while, you’ll be familiar with the “user bar” which is shown directly under the main date heading:

The "user bar" in previous versions of MIDAS
The previous “user bar” in earlier versions of MIDAS

The “user bar” indicated who was signed in, and provided options to sign out, change your password, access help, or make MIDAS go fullscreen. You could also click your name to show a list of all the devices you were currently signed in from.

We’ve decluttered this area for v4.41. Now, just your name will be shown under the main date. You can select your name and a new drop-down list will appear:

New User Drop-Down in MIDAS v4.41
New User Drop-Down in MIDAS v4.41

This new drop-down contains the following options:

  • Your Current Sessions – view details of all the devices you’re currently signed into MIDAS from, and remotely sign out any you’re not actively using.
  • Your Details – as v4.41 introduces new permissions allowing users to change their name or email, the previous “Change Password” link has now become a “Your Details” option in the new drop-down. Depending on the permissions assigned to your account, this option will allow you to change your display name, password, or the email address you use to access MIDAS.
  • Full Screen – quickly enter or exit full screen mode.
  • Help – open the help documentation.
  • Sign out of MIDAS – instantly sign out at any time.

New icons

You may have spotted some new icons alongside the options in that new user drop-down above.

Well, this isn’t the only place you’ll see some new icons in MIDAS v4.41. We’ve also created a new set of icons for the options on the main administration creen:

New icons on the MIDAS Admin Options screen
New icons on the MIDAS Admin Options screen

Previously all the options on this screen used the “cog” icon used for the “Manage MIDAS” option. We felt it was about time for a refresh, and that each of the options on this screen deserved their own unique icons.

Improved graphs with tooltips

In case you missed our post a few days ago, for v4.41 we’ve rewritten the graphics code that MIDAS uses to generate graphs on the statistics (reporting) screen.

Graphs now have tooltips
Graphs now have tooltips

Bar graphs and pie charts now show tooltips when you move your cursor over each segment. Furthermore, we’ve also adjusted how dates are shown along the bottom axis in bar charts to prevent overcrowding.

Info, Tips, Warnings, and More!

The help documentation has also had a bit of makeover for v4.41. Not only have we improved its accessibility, we’ve also made some visual changes.

Throughout the documentation you’ll see coloured boxes with either additional information, helpful tips, warnings, or links to more resources.

Here’s how these looked in the documentation before v4.41:

Info Boxes pre-v4.41

…and here how these look now:

New Info Boxes in MIDAS v4.41

It doesn’t end there!

Whilst these might be the main UI/UX improvements we’ve made for v4.41, we’ve also made numerous other small improvements to the user interface and user experience in our latest update – too many to list here!

So whilst we’ll continue to add exciting new features and functionality with every new release, we’ll also be working to continually improve your user experience too!
