Thexyz email migration to open-source environment

Thursday, June 9, 2022

Later this year, we will be making significant changes and improvements to Thexyz email. This announcement will serve as a reference for a timeline to this change, and a resource to answer many common questions. 

Thexyz Webmaill has been with us for many years and to encourage future development and talent, we are adopting an approach to incorporate open-source software over closed-source and proprietary projects. This means that we will no longer be offering our MobileSync service built on Microsoft ActiveSync. Instead, we will adopt open standards such as CalDav and CardDav to allow for greater flexibility and community-driven development. This upgrade will take Thexyz email further toward a collaboration and communications platform, including secure email, powerful calendars, contact management, cloud storage, and online office features.

What features are remaining the same?

No, the price you pay will remain the same and you will continue to receive the same service and support you receive today.

Do I need to change my domain's DNS settings?

No, the settings for MX,SPF, and DKIM will remain the same.

Do I need to change the IMAP, POP, or SMTP server or port settings?

No, the settings will remain the same.

Will the contact books that users created in webmail be migrated?

  • MobileSync (ActiveSync) will be replaced by support for open standards (Caldav/Carddav)

Which features are being removed?

Split domain routing (SDR)

Starting July 2022, new configurations will not be available. If SDR is configured for a domain, it will remain until you disable it, or we start migrating Thexyz Mailboxes. SDR will be removed for all domains when we start migrating Thexyz Email users.

Domain catch-all

Starting June 2022, new configurations will not be available. If a catch-all is configured for a domain, it will remain until you disable it, or we start migrating Thexyz Webmail users. Catch-all will be removed for all domains when we start migrating Thexyz Webmail users.

Webmail identities

Starting June 2022, new configurations will not be available. If an identity is configured it will remain we start migrating Thexyz Webmail users.

BCC archiving

As announced previously new configurations are no longer available. If BCC is configured for a domain, it will remain until you disable it, or we start migrating Thexyz Webmail users as per the timeline below. As an alternative for BCC archiving you can use Thexyz Email Archiving. BCC will be removed for all domains when we start migrating Thexyz Webmail users.

Admin Reply/Forward Control

Starting June 2022, Administrators will no longer have access to configure Out of Office auto-reply or mail forwarding via the Control Panel. 

Spam Settings

Starting June 2022, Administrators will no longer be able to set spam settings. The new spam delivery behavior will deliver spam messages to the recipient’s spam/junk folder. This specific change applies to both Thexyz Email and Hosted Exchange. To gain additional control over spam behavior, administrations can upgrade a domain to our spam filtering add-on.

Allow/Block Lists

Originally we planned on removing the Administrators ability to configure the domain level allow/blocklist via the Control Panel. We took your feedback into consideration and found a way to keep this feature.

Starting July 2022, Administrators will no longer have access to configure allow/blocklist behavior at a domain level via the Control Panel or API. This specific change applies to both Thexyz Email and Hosted Exchange. The domain level safelist and blocklist (Except IP’s) will be added to each mailbox on the domain.

The new configuration will have a default limit of 250 entries for each mailbox independently. If the list is larger than 250 entries when the mailbox is migrated it will be truncated so it does not exceed the limit.

  • The ability to configure allow/blocklist behavior at a mailbox level via the Control Panel will be retained.
  • Limits of 250 entries will be applied to the Allow list and the Blocklist independently.
  • IP addresses or ranges will no longer be a valid list entry on the Allow list or Blocklist.
  • Administrators are advised to upgrade domains to our spam filtering add-on.

What is the timeline for this platform upgrade?

  • May - August 2022: Preparing to migrate mailboxes.
  • April - September 2022: Update the Thexyz Email feature set to ensure compatibility with our upcoming platform change.
  • October 2022 through March 2024: Migrate all mailboxes to the new environment.
