Hi,
I am working on setting up a mail server using Dovecot and Postfix on Debian Squeeze. So far I am able to connect to secure IMAP via Dovecot, and I am able to receive emails. However, I am unable to get Postfix to accept authentication for SMTP. My email client at home can make the connection initially, but then complains that the server doesn't support authentication and refuses to send messages.
Here are the lines that show up in /var/log/mail.log when I try to send to send a message (my IP is replaced for security):
Code:
Aug 31 18:55:23 li283-45 postfix/smtpd[29732]: connect from pool-XXX-XXX-XXX-XXX.pitbpa.fios.verizon.net[XXX.XXX.XXX.XXX]
Aug 31 18:55:34 li283-45 postfix/smtpd[29732]: lost connection after AUTH from pool-XXX-XXX-XXX-XXX.pitbpa.fios.verizon.net[XXX.XXX.XXX.XXX]
Aug 31 18:55:34 li283-45 postfix/smtpd[29732]: disconnect from pool-XXX-XXX-XXX-XXX.pitbpa.fios.verizon.net[XXX.XXX.XXX.XXX]
I've tried doing a google search, and everything suggested stuff with my sasl settings in main.cf, none of which worked (though I did apt-get install all the needed sasl packages). My current /etc/postfix/main.cf:
Code:
