Hi All,
I have strange problem with my mail server behind ISA server(integrated
Mode). I have SMTP server on IIS(on a different PC) with Invalid IP and is
published behind ISA server using Mail wizard as secure NAT client. I find
lots of Spam mails going out from this mail server using external IP address
of ISA server. I have enabled SMTP filter on ISA, but i doubt its working or
not?
I find following messages in my Event viewer of ISA server continously.
THE SMTP command exceeded its length.
In details it shows as mail from some xyz@xxxxxxxxxx
Please advice as my Event viewer is full of such messages. Is it any kind of
Mail attack? What has to be done to stop such activity.
Please help me out. I have configured SMTP filter to block messages
containing spam but they still get through. please advice of some other ways
to prevent ISA from relaying.
Regards,
Vinay.
