Trying to get authentication on my mail server (ubuntu 10.04) running but am having trouble. I have a server with postfix for smtp setup, imap server with courier setup. My postfix authentication is using cyrus (I haven't tried dovecot really) saslauth. The user name and password is stored in a MySql database. Logging in with imap-ssl works on a remote client (thunderbird), and I can read my mail. I can't get the SMTP side working, and have focused the issue down to saslauth. Testing with testsaslauthd -u 'username' -p 'passowrd' -s smtp returns connect() : Permission denied the password in the database is encrypted and I guess this testsaslauthd will take a plain text password and encrypt it. Looking for someone to walk me through getting this working. Im new to the mail server, and have never got one fully working. Thanks. Ask me which log files I should look at/post, which tests to run, permissions to check.
