[OpenSIPS-Users] Scheduled Maintenance: OpenSIPS Mail Infrastructure Migration – September 22

[Răzvan Crainea]

Hi everyone,

On Tuesday, September 22nd, 2026, starting at 10:00 EEST (09:00 CEST / 
08:00 BST / 07:00 UTC), we will be performing a migration of the 
OpenSIPS mail infrastructure.

During the maintenance window, which is expected to last approximately 3 
hours, the following services will be temporarily unavailable:

* all @opensips.org email addresses;
* mailing lists hosted under lists.opensips.org;
* delivery and access to the OpenSIPS community mailing lists.

This migration is part of a broader infrastructure upgrade. We are 
moving the mail services to a newer, more efficient and more flexible 
platform, which will simplify maintenance and make it easier for us to 
expand and improve the infrastructure as the OpenSIPS community grows.

Mail sent to the affected addresses and mailing lists during the 
maintenance window may be delayed until the migration is complete.

We will work to restore all services as quickly as possible and will 
announce once the migration has been completed.

Thank you for your understanding and patience.

Best regards,
