Title: dnf-automatic breaks postfix mysql maps on CWP
Post by: Watchdog on August 01, 2026, 09:47:12 AM

Heads up if you're running CWP with dnf-automatic installed for unattended updates: its first run silently swapped out CWP's custom-built postfix (compiled with MySQL support for virtual mailboxes) for the plain AlmaLinux baseos version, which doesn't have MySQL map support at all.

Mail started failing with "temporary lookup failure" on every message needing a virtual alias lookup.

Fixed it by finding the transaction(In my case 109) that did the swap in CWP's Yum Manager (under Yum History) and hitting Rollback to get the CWP build back. Also had to manually recreate /usr/lib64/postfix since it got left behind during the version change and postfix wouldn't start without it.
