Like a good doobie, I applied the Apple security update last night. Little did I know that one of the fixes would debilitate the mail server. It kinda looked like a firewall problem, and after poking around a TON, I finally found that the security update had (apparently) made a change to my Postfix configuration.
Now, I can claim some responsibility for this little outage, as I didn’t look at the notes for the update before applying them. Guess I’ve got a little too much trust in Apple.
Anyway, it’s working again, so now the spammers have another target available again. 🙂
