User kysil posted this question a couple of months ago but never got an answer, and the topic is closed (so I can't reply to it).
I am also looking to update the Postfix version included in iRedMail. Specifically, I'm looking for SMTPUTF8 support (as specified in RFC 6531), which is only available starting in v3.
Is there a way to do this?
