I am encountering 'transport problems' in postfix, and I can't tie them down. I'm beginning to wonder whether I have conflicting settings in the various parts of the mail server. I have been advised separately by a number of people, so it is entirely possible. I am, therefore, attempting to check every detail of my setup.
I was advised to put 'MAIL=/home/$USER/MailDir:INBOX=/var/spool/mail/$USER' into /etc/profile 'because that's the way that dovecot likes it'. Is this correct? I'm using 0.99.14 on Fedora Core 4.
Dovecot does appear to be working correctly. I can drag messages to the mailboxes. The problem appears to be in postfix. Fetchmail can download the messages, but they are sticking in postfix's queue. I'm still working on that, but would like confirmation that I was right to follow the advice given above.
