Love is a MTA called postfix

[sawyl]

After a day of stressing over a yet another urgent OS upgrade, I found myself forced to spend my evening reconfiguring my mail server following my ISP's decision to migrate to Exchange. I'd been dreading the change, thinking my mail server still ran sendmail. But to my surprise I discovered that it was running postfix, making it a breeze to reconfigure.

All I had to do was:

1. change fetchmail to point to the new POP server along with the old one
2. change /etc/postfix/sasl_password to add my username and password for the on the SMTP server
3. run postmap hash:/etc/postfix/sasl_passwd to rebuild the DB file
4. change relayhost in /etc/postfix/main.cf
5. bounce the fetchmail and postfix
6. send myself a couple of test messages

And it all worked like a charm. It's days like this that make me feel like I might actually be worthy of counting myself a professional sysadmin...
