I am pretty new to Dovecot and totally new to LMTP. I have normal delivery working but I am struggling with aliases. In my mail queue I am seeing things like:
But in my /etc/aliases, I am aliasing clamav to nick and nick@mydomain.com is a valid mail box that can receive normal mail.
The corresponding line in the mail log is:
2024-10-26T14:55:56.385500+01:00 mail-www dovecot: lmtp(1371485): Error: lmtp-server: conn unix:pid=1371484,uid=102 [1]: rcpt clamav@mydomain.com: Failed to initialize user: Mail access for users with UID 107 not permitted (see first_valid_uid in config file, uid from userdb lookup).How do I get round this issue? I can drop the minimum UID to 0, but then all system users are deemed valid for mail which is not true. None of them are.
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_
