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
sendmail -bvtest@example.com test@example.com... deliverable: mailer esmtp, host example.com., usertest@example.com
Something like this should show the alias.
Weird.
root@mail-www:~# sendmail -bv nick@mydomain.com
Mail Delivery Status Report will be mailed to <root>.
root@mail-www:~# sendmail -bv clamav@mydomain.com
Mail Delivery Status Report will be mailed to <root>.But my aliases are:
# See man 5 aliases for format
postmaster: root
clamav: nick
# Webmin: Redirect root to nick
root: nick'newaliases' has been run and /etc/postfix/main.cf has the line:
alias_maps = hash:/etc/aliases
