The relay is "virtual" ... I am digging now if the edited sql-queries somehow changed the transport for this domain.
Maybe I am completely wrong. dunno yet.
that seems to be the issue
this _is_ the issue. ;-) Thanks for the log and that's why I asked for LMTP and Sieve entries in it. If there are no such entries, then LMTP is not used and your Dovecot/Sieve setup has no effect.
In postfix we have:
virtual_transport = lmtp:unix:private/dovecot-lmtp
That worked for years.
That's still working. But if you have an entry for one/several domain(s) in the transport table, this will overrule it for them.
