That processed the queue and it has all come through. I was trying "postfix flush" and "postqueue -f", neither of which worked.
It seems like setting virtual_alias_maps wat the fix.
I'll keep an eye on it in case it recurs, but I have to wait for system emails.
Thanks,
NIck

Mail already in the queue will need to be reprocessed with postsuper -r ALL
Or just delete it and test again.

OK. I have tried setting:
virtual_alias_maps = $alias_mapsThat’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:

Post aliases are implemented in the local delivery agent. To use lmtp,

Postfix does not expand aliases with sendmail -bv, just reports if the address will be accepted.

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 :)
