This is pointless because he's complaining about cron and system emails which use the sendmail command are submitted through the pickup service, not port 25/smtp (in fact, if you're submitting any mail via port 25 you're doing it wrong but that's another discussion). TE Dukes: Please do the following (lines that start with # should be run as root, lines that start with $ should be run as a local user): Install the mail command which is an easy interface to the sendmail command and thus the pickup service. # yum install mailx # tail -n0 -f /var/log/maillog ...then in another window (replace someu...@example.com with your own email address): $ mail -s 'Test Email' someu...@example.com <<< "This is a test" ... wait a minute for postfix to have a chance to process and send the message, then break out of the tail command and copy/paste the output into your reply. Then also copy and paste the output of the following: $ postconf -nf; postconf -Mf If I need any more info after that I'll let you know.
