I cannot send or receive any emails from my server. I have checked the mailq and it has over 1100 emails. I have tried to run the following to flush the queue:
But I get this error:
postqueue: fatal: Cannot flush mail queue - mail system is down
The mailq is full of emails from 'root' to 'root'. I have provided the maillog and mailq entries below. Does anyone know what could have happened?
I am running CentOS 5.5.
