ACK. That's the status quo and we're working with the hoster to (permanently)
fix this. The platform itself consists of two mail servers for redundancy.
Both have IPv6 address

Nope!
I don't see any reason to disable ClamAV completely. What I would definitely
would to is *not* use the command line scanner utility clamscan to scan
messages for malware. This

Greetings,
is it a valid mail address if the domainpart ends with a trailing dot. e.g.
like this: recipi...@example.com.
AFAIK in DNS a trailing dot in a domain name is valid and we omit it usually
because it's said to be implict.
TIA,

Greetings,
I was wondering if there's something similar to warn_if_reject when it comes
to dry-run / test-run MILTER applications in Postfix. The documentation on
warn_if_reject does not mention MILTERs, which usually means the feature isn't
there because otherwise it would be documented, and the
