Could be just a malicious mail bomb, intention being to bring your
server to its knees while rejecting all those mails, if they are at
high enough rate.
There is no defense, since you can't stop them sending / D o S ing you.
The best is to have an upstream box like a packet filtering router
and block at level of tcp/ip source address, or an IMGate and block
at smtp level on headers or contents. This will definitely slow down
imgate, but that' what it's there for, to take catch the flak for
imail so your customers can get to your Imail services.
