I recently changed a DNS setting and the system got bombarded with spam (going from 600msg a day to over 10000 in a couple hours).
The Greylist service states that it is in a "CRITICAL" state (I'm assuming this means it isn't running).
The queues, mainly the filtering queue, has several thousand e-mails waiting to be processed.
Any ideas why the system would react this way?
If you want to see a log, just let me know what log you want to see and I'll e-mail it to you.
Thanks, in advance.

As you can see, the greylist services are stopped.
Code: Select all
> aptitude install mc-greylistd
and try to start it manually:
Code: Select all
> /usr/mailcleaner/etc/init.d/greylistd start
I see your system is getting overloaded because it doesn't have enough memory.
512MB is definitively not enough for a production system. It is actually swapping and the gets too high. That's why you can't process messages fast enough.
I looked at the /var/mailcleaner/run/greylistd directory, and from another post, found that the file 'socket' was there, even when the service was not running.
I removed the 'socket' file and the process started.
The environment is still in 'test' mode, due to problems like I have had, however, your point of "512Mb of memory is not enough for a production server" is valid.
I am going to see if I can 'scrounge' an extra 512Mb for each of the two systems that are running.
Q: What does the red (*) mean next to a service?
If I restart the service, it goes away. But, I'm wondering if that means it's status is unknown or not?!?
