Just when you thought it was safe to send email! I've been trying to setup a debian sarge postfix server with mysql virtual hosts/accounts. I've so far gotten postfix up and happy, amavis doing all my checking, dovecot serving out imap, and postfixadmin running for account management. Very nice. Now if only I could get SMTP to work. I find that there are many ways of getting smtp going with virtual accounts. I'm avoiding PAM and saslauthd because you have to store the passwords in mysql as clear text. This lead me to courier authdaemon package. I've got authdaemon configured and running. I've created the file /etc/postfix/sasl/smptd.conf with the following: cat /etc/postfix/sasl/smtpd.conf pwcheck_method: authdaemond log_level: 3 mech_list: SQL authdaemond_path:/var/run/courier/authdaemon/socket I have created a link to the socket in the postfix jail: ls -l /var/spool/postfix/var/run/courier/authdaemon/socket srwxrwxrwx 1 daemon daemon 0 Sep 28 11:09 /var/spool/postfix/var/run/courier/authdaemon/socket And I have added the postfix user to the daemon group: grep daemon /etc/group daemon:x:1:postfix Now when I try to send a message I get the following error: fatal: no SASL authentication mechanisms Everything I find seems to say that the reason I get this message should be because I don't have the postfix/sasl/smtpd.conf file. BUT I DO! Can anyone help point me in the right direction with this? I feel like there is just one small connection missing between postfix and the authdaemon process. Thank you so much for any help.
