Hi Zhang:

Postfix 2.11 stopped to be officially supported back in January 2018 and does not receive updates any more. When can we expect a Postfix 3.0 (or better even 3.3) package from iRedMail to be able to update to?

We would need the "check_sender_a_access" config option, which is available from 3.0 and up only.

If an iRedMail Postfix 3 package is not planned: Are there any expected problems if we use a foreign RPM package for the update and which repo would be recommended for that?

Thanks
