Postfix suddenly stopped working

[Petr Janda]

Ok, it started working again. Its beyond me. I ran the snmpd process 
with the -v flag and it told me the process was exiting because of bad 
boolean configuration, so i checked my main.conf and it had typo in it 
which i accidently left there as I was trying to debug postfix last 
night, that was long AFTER it stopped working. Well I fixed the typo and 
it works again.

Seems rather confusing...
