Steps to reproduce the behavior:

  1. Update vie apt to 4.0.0-1620639143.9e157feb.buster
    Setup office365 integration / normal IMAP setup also fails.

I’ll be ignoring this topic in favor of this issue: Error on sending E-Mails (incompatible encoding regexp match) · Issue #3552 · zammad/zammad · GitHub
Looks the same. Feedback will be provided in the issue by our verification process.

The latest build I tested with Centos7 does not fix this…

update added to Github.
