OS: Fedora 14 (i686) Issue: Postfix deferring mail delivery with the following log entry: Dec 26 09:50:43 server1 postfix/error: C023232006B: to=<email@example.com>, relay=none, delay=24641, delays=24640/0.32/0/0.01, dsn=4.4.2, status=deferred (delivery temporarily suspended: lost connection with 127.0.0.1[127.0.0.1] while sending DATA command) Where I think the error is actually occuring: Dec 26 09:50:43 server1 amavis: (02190-01) (!)connect_to_sql: unable to connect to DSN 'DBI:mysql:database=mail;host=127.0.0.1;port=3306': Can't connect to MySQL server on '127.0.0.1' (13) Dec 26 09:50:43 server1 amavis: (02190-01) (!!)TROUBLE in process_request: connect_to_sql: unable to connect to any dataset at (eval 100) line 241, <GEN13> line 5. Dec 26 09:50:43 server1 amavis: (02190-01) (!)Requesting process rundown after fatal error Steps I have taken to this point: Checked /etc/amavis/amavis.conf to make sure the sql password and user is correct. I used the same user as the how-to and added my password. The password is correct. Logged into my sql on host 127.0.0.1 using amavis db (mail_admin) user and password, the connection was successful and a mysql prompt was provided. I checked /var/log/secure for entries that demonstrated failed logon and there are none. Any ideas what my problem may be? Great how-to thanks for posting it.
