My problem is that I cannot authenticate through SASL against a MySQL database via Postfix to send mail SMTP(S). I have been trying to figure this out for over a week and have read many of the other posts without finding a solution. A couple days ago I started over with a fresh install. I have installed Feisty Fawn server i386. I used Falko's "The Perfect Setup - Ubuntu Feisty Fawn" guide @ http://www.howtoforge.com/perfect_setup_ubuntu704 up until the point where the SSH server is installed. Then I switched over to Falko's "Virtual Users And Domains With Postfix, Courier And MySQL (Ubuntu 6.10 Edgy Eft)" and I believed I followed everything in that guide to the 'T'. I have tested every part of the server and the only issue I have is that I cannot send mail (unless I use the command line). The issue I have is most related to section http://www.howtoforge.com/virtual_postfix_mysql_quota_courier_ubuntu_edgy_p3 /etc/default/saslauthd, /etc/pam.d/smtp, /etc/postfix/sasl/smtpd.conf all seem to be correct (exact copies except my server info). I've tried numerous little changes and restarts/reloads. But nothing seems to work. Before I started changing things I made a backup of each file. I have reverted to those backups and done a system restart. This is what /var/log/mail.log looks like after I try to send something via Thunderbird: Code: May 12 07:56:09 MY_SERVER postfix/master[5678]: reload configuration /etc/postfix May 12 07:56:16 MY_SERVER postfix/smtpd[7776]: connect from REMOTE_COMPUTER_NAME[IPADDRESS] May 12 07:56:19 MY_SERVER postfix/smtpd[7776]: warning: SASL authentication failure: cannot connect to saslauthd server: No such fi le or directory May 12 07:56:19 MY_SERVER postfix/smtpd[7776]: warning: SASL authentication failure: Password verification failed May 12 07:56:19 MY_SERVER postfix/smtpd[7776]: warning: REMOTE_COMPUTER_NAME[IPADDRESS]: SASL PLAIN authentication f ailed: generic failure May 12 07:56:20 MY_SERVER postfix/smtpd[7776]: warning: SASL authentication failure: cannot connect to saslauthd server: No such fi le or directory May 12 07:56:20 MY_SERVER postfix/smtpd[7776]: warning: REMOTE_COMPUTER_NAME[IPADDRESS]: SASL LOGIN authentication f ailed: generic failure May 12 07:56:21 MY_SERVER postfix/smtpd[7776]: disconnect from REMOTE_COMPUTER_NAME[IPADDRESS] I did look at the log after turning on verbose logging. Since that didn't seem to shed any light on my issue I won't bother posting that unless someone would like me to. ps aux | grep saslauthd outputs: Code: root 7666 0.0 0.1 6464 748 ?

Let me know if you have any ideas. Thanks you very much!
Solved WOW!!! I feel so stupid yet happy! After posting howtoforge listed similar threads and I had not read this one: http://www.howtoforge.com/forums/showthread.php?t=12608 In /etc/default/saslauthd, commenting out Code: PARAMS="-m /var/spool/postfix/var/run/saslauthd -r" and adding Code: OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r" Solved everything!
I had the same problem with saslauthd being unable to login for sending emails. I resolved it by editing the /etc/postfix/sasl/smtpd.conf file: Change: To: Seems inconsequential, but it worked.
