Please find the following system requirements for:

Can you install atmail 7 for us?

Yes. We can remotely help to install atmail 7 for you, for an additional fee. Large installations will require a custom quote. Please contact our sales team.

Can I install atmail on my web hosting account plan?

Yes. The atmail 7 webmail client installs easily on most Linux hosts. However, the installation for atmail email server requires root access to the server, which is prevented by the limitations on the shared hosting plans offered by some web hosts.

We recommend dedicated, virtual dedicated or virtual private server plans if you're considering atmail email server. Please contact the web host you are considering beforehand and talk to them what you want to do. They can usually offer advice on what plan offers the features that you might need.

For further information, please refer to our atmail Installation Guides:

How do I manage my atmail email service?

Our web admin has a wizard that will walk you through on your first use. For further information, please refer to our Help Centre for step by step tutorials. 

Can you log into our system to help us with "X"?

Yes, we usually can. We offer on-demand, remote, support services for an additional fee. (The fee may not apply if the issue is due to an atmail issue.) To submit a remote support request, please log into our client portal and select the appropriate support option from the interface.

Is it possible to manage more than one IMAP account at a time with the webmail client?

No. Our atmail 7 webmail currently only supports access to one account at a time. 

How do I backup or restore atmail for an on-premises account?

atmail 7 on-premises makes use of OS-level tools to make backups easy and flexible. Please refer to the Backup and Recovery information in our Help Centre for full instructions. 

The "Licence" tab in Web Administration asks for a DownloadID and serial key, but the email I received had a serial key and an atmail ID (or ClientID). How do I get a DownloadID?

Your atmail ID, DownloadID and ClientID are interchangeable. You can safely use whichever ID you received in the "DownloadID" field in Web Administration > Licence tab > Register Licence. 

Can I use filters to have an email forwarded to an email inside and/or outside our domain?

No. Such filters only move messages between folders. 

Can we run redundant or clustered servers on the same on-premises licence?

Yes. Our atmail 7 on-premises licence provides multi-server support for full active/active redundancy and clustering support. 

Can atmail 7 check multiple mailboxes at once?

Unfortunately, this is not currently possible through the atmail 7 webmail client. While atmail 7’s email server has an alias feature which can deliver a copy of emails received at a single inbox to multiple addresses, sending emails separately from multiple and/or external accounts currently requires logging out of one account before logging into another. 

Will my antivirus and antispam still get definitions and RBL updates if my support and upgrades expire?

No. The antivirus and antispam signatures are pulled from the atmail network and are deactivated if your support and upgrade period has expired. 



Is atmail 7 compatible with Windows clients?

Yes, most Windows email clients can connect directly to atmail's IMAP/POP3 server. Outlook users can synchronise calendars and contacts using a third party plugin such as Outlook CalDav Synchronizer. Thunderbird/Mozilla users can connect their contact and calendar clients directly to atmail's CalDAV/CardDAV server. The webmail UI is supported under Windows IE8+.  

Is atmail 7 compatible with Mac OS X clients?

Yes. OS X mail users can connect directly to atmail 7's IMAP/ POP3 server and connect native Apple Calendar and Contacts clients directly to atmail 7’s CalDAV/ CardDAV server. 

Is atmail 7 compatible with iOS clients?

Yes. iOS mail users can connect directly to atmail 7's IMAP/ POP3 server and connect their iCal and Address Book clients directly to atmail 7's CalDAV/ CardDAV server. atmail 7 also provides iOS provisioning support, optional Exchange ActiveSync support and a mobile friendly UI.

All Third-Party Client documentation can be found here



Can atmail run on cPanel, Webmin, DirectAdmin or other control-panels?

Yes, atmail 7 can be installed on most control panel equipped webservers, according to our Webmail Client Installation Guide. You can also integrate additional functionality into your selected control panel (e.g. Sieve email filtering, change passwords and set auto-reply) by using the atmail API and plugin framework. However, please understand that we cannot directly support anything outside our own atmail product on these installations. 

Can atmail 7 work with Plesk?

Yes. atmail 7 can be installed (according to our Webmail Client Installation Guide) under Plesk, like any regular PHP application, to provide the full webmail client, calendar and contact features to end-users. However, please understand that we cannot directly support anything outside our own atmail product on these installations. 

Does ActiveSync work with Plesk?

No. Plesk servers do not support ActiveSync. 

Does ActiveSync support HTML email?


Can atmail run on KVM/VMware/Xen?

Yes. atmail 7 runs well in KVM, VMware, Xen and most other "full virtualisation" environments. Please contact our sales team if you would like to confirm for other environments. 

Can atmail run in OpenVZ/ Solaris Containers?

No. We recommend using atmail 7 under a KVM, VMware or Xen environment. 

Can atmail be installed on Amazon ECS/ AWS or other cloud hosting plans?

Yes. Although these environments sometimes provide other considerations that can affect performance. (e.g. The IP addresses of some cloud hosting plans are subject to reassignment at unexpected times, which can cause issues with static MX/DNS records, including mail delivery deferment or failure.) We recommend reading the technical details of such plans carefully and installing the evaluation copy of the software if you are not sure. 

Can atmail run on (Solaris/ Slackware/ Gentoo/ or any other unsupported OS's)?

The webmail client "should" work correctly on any OS that supports all the PHP dependencies. However, variations in the default shell can cause script issues. Dependencies may also have different names or default paths (or both) on unsupported systems.

The same goes for the email server version of atmail 7. We use open-source components such as Exim, Dovecot, SpamAssassin and ClamAV for atmail 7's core services to allow the most flexibility. These servers' binaries are compiled from source during system installation and are all platform-independent.

However, the above-mentioned issues would probably require that each component of atmail 7’s email server be installed manually, which could also cause other issues.

This leads to the main issue: "not a supported configuration". You can try to install on these OS's, but we will not be able to assist with most issues encountered during installation, maintenance or upgrades. This is the primary reason we recommend choosing a "standard" GNU/Linux OS configuration, because we are more able to quickly and easily help you, as well as identify any issues that may be affecting other clients on similar systems. 

Does atmail 7 support LDAP/ Active Directory for authentication?

Yes. Our atmail 7 email server can check user authentication credentials against an LDAP/ Active Directory server before allowing users to log in. Setup is easy. Please see our Directory Services Configuration Guide for LDAP/ Active Directory setup instructions. 

Do you have any integration with SSO providers such as OneLogin?

No. atmail 7 does not come out-of-the-box with Single Sign-on (SSO) provider integrations. Please contact our sales team to enquire about our professional services to help customise your installation. 



Will my atmail 7 on-premises subscription renew automatically?

No. Our sales team will contact you prior to renewal, but feel free to contact our sales team prior, if you’d like to discuss your renewal earlier. 

Does atmail 7 on-premises work without renewal of licence?

No. If an on-premises licence is not renewed, you will receive a “Licence expired” message when you next log in to webmail or your web admin and your access will be restricted. 

How can we access an extra week to sort out an on-premises renewal?

Please contact our sales team, who can usually help organise a temporary on-premises licence to cover any gap between your licence expiring and the receipt of your renewal payment. 

Can I migrate from atmail 7 to the new atmail suite and/or atmail mail server on-premises? 

Yes. atmail 7’s end of life will be 31 July 2019, so please contact our sales team soon.
