OK. I have tried setting:
virtual_alias_maps = $alias_maps
That’s not likely to work. The file format is different. No “:” in virtual_alias_maps
Also, it’s best if you use fully qualified addresses.
clamav@domain root@domain root@domain nick@domain
Use your domain of course.
And in /etc/aliases I now have:
# See man 5 aliases for format postmaster: root clamav: root # Webmin: Redirect root to nick root: nick@mydomain.comAnd the mail queue won't clear:
2024-10-26T18:04:00.890009+01:00 mail-www dovecot: lmtp(1404363): Error: lmtp-server: conn unix:pid=1404358,uid=102 [1]: rcpt root@mydomain.com: Failed to lookup user root@mydomain.com: Invalid settings in userdb: userdb returned 0 as uid 2024-10-26T18:04:00.892965+01:00 mail-www postfix/lmtp[1404358]: 4426B7062BF: to=<root@mydomain.com>, relay=mail.howitts.co.uk[private/dovecot-lmtp], delay=7518, delays=7517/0.11/0.07/0, dsn=4.3.0, status=deferred (host mail.howitts.co.uk[private/dovecot-lmtp] said: 451 4.3.0 <root@mydomain.com> Temporary internal error (in reply to RCPT TO command))Am I too late for the destination address to get rewritten, so should I just purge the mailq and get some new test messages?

Post aliases are implemented in the local delivery agent. To use lmtp, put your aliases in virtual_alias_maps
Postfix does not expand aliases with sendmail -bv, just reports if the address will be accepted.

I think it is more common to have your MTA postfix/sendmail do the translation to aliases, so before you deliver it to lmtp. Maybe test if your MTA is indeed sending the alias this log snipped above is not mta issues at all
i will take the possible problem later when dovecot does not say first_ Hi, I get:
root@mail-www:~# doveconf -n | grep first_valid_ first_valid_uid = 1000set it to 100 then, not 1000
107 is lower then 1000, no ?
root@mail-www:~# doveconf -n | grep last_valid_ root@mail-www:~#why is last not set ?
Is this not valid? My first proper user is user 1000. All users below that are system users and should never receive emails as themselves and need to be aliased to a proper user. Or have I misunderstood. in that case its ok to have 1000 as first_
do you change uid gid in userdb ?
TBH, I would have thought postfix may have rewritten the RCPT TO before it sent on to LMTP but that is said without knowledge.
At the same time I have received in my proper mailbox an email from root to clamav so I am massively puzzled. solve doveconf first :)
