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

[Răzvan Crainea]

Hi everyone,

The OpenSIPS mail infrastructure migration has been completed 
successfully, and all affected services should now be back online.

This includes:

* @opensips.org email addresses;
* mailing lists hosted under lists.opensips.org;

The services are now running on the new infrastructure, which gives us a 
more efficient and flexible platform and should make future maintenance 
and expansion considerably easier.

If you notice any issues with email delivery, mailing-list 
subscriptions, archives, or any other related service, please let us know.

Thank you for your patience during the migration.

Best regards,
The OpenSIPS Team
