Re: [Dovecot] Dovecot Antispam Problem (Using mail sending backend)

Actual sendmail only lets the trusted users send mail with a different "from" than the user running the command. So if user "x" is trying to send something but trying to say it is from user "y" (maybe postmaster), sendmail won't allow it unless user "x" is in trusted users.

Hmm, mine doesn't check the "From:" header line but rather the envelope sender which we don't set (so the local user should be used)
