Dear Friend,

Thank you very much for your interest in Axigen.

Beyond conversations support, the new X4 also introduces Dark Mode, which you can switch to automatically or let the WebMail do it for you.


Organize Emails by Labels

Manage your labels and apply them to your emails and conversations. Search by label or define rules to get your labels automatically applied based on various criteria.

Express Yourself with Emojis

Add more feeling to your emails and notes with the new built-in emoji. Quickly select from your list of recent ones or search for the right emoji by using specific keywords.

Refer Others via @mentions

Add friends or co-workers to your conversations by @mentioning them while composing — type an “@” followed by a character and quickly choose from your contacts via auto-complete.

Create Rich Content Faster

Format your content faster, plus add inline images using the new, dedicated button and the redesigned HTML editor toolbar, now offering an optimized user experience.

Important Notes & Upgrade Information

Back up before upgrading. Axigen X4 starts a series of storage upgrade jobs. As always, we strongly recommend you to perform a full Axigen backup on your current version before the upgrade.

Performance impact on initial index creation / upgrade. This version has a number of index changes: the sort indexes have been modified and will be recomputed at upgrade time; in addition, we have introduced a new conversation index — used for the new conversation view — which will also be computed in sequence, after the sort indexes. These upgrade jobs are expected to last a few hours (depending on your storage size) and will require a storage capacity increase of up to 10%. WebMail and IMAP user access is conditioned by the sort indexes, while the conversation indexes are only used by the WebMail. Until they are created, users will be able to use the WebMail in mail view.

Kaspersky End of Life. Starting with X4 (10.4.0), Kaspersky AntiVirus and Kaspersky AntiSpam are no longer available. We recommend Kaspersky customers to switch to Axigen AntiMalware & AntiSpam (powered by Bitdefender). Contact our sales team for a commercial offer.

Outlook Connector End of Life. Starting with X4, the Outlook Connector will no longer be supported. We've put a lot of additional effort in the Axigen WebMail, which is now our main recommendation in terms of clients. Alternatively, for users who still want to stick with Outlook, you can use it via IMAP; for calendar support, some of our end-users are already using the CalDAV Synchronizer plug-in.

Custom WebMail themes. As part of the new Dark Mode support, we've introduced significant changes to the existing WebMail stylesheets, including an extended range of colors. If you're using a customized WebMail theme, you will have to extend and adapt your customizations to also apply in Dark Mode.

No longer supported platforms. The following platforms are no longer supported: CentOS 7, CentOS 8, Red Hat Enterprise Linux 7, Oracle Linux 7, OpenSUSE Leap 15.1, Ubuntu Server 18.04 LTS, OpenSUSE Leap 15.3, Debian 10, Windows Server 2016.
