Mailscanner marking DOS Attack on 2 different servers

Greetings.

I have two different servers that just started developing problems with
mailscanner marking all inbound and outbound email a denial of service
attack.

I've been searching the archives trying to figure out what could be wrong,
but can't really find anything. It seems that maybe it's caused by a timeout
on dns, but nothing has changed on these two servers in many weeks.

Where else could I start troubleshooting this?

Thanks.
