Queues jammed with relay spam.

[JimSills]

I implemented the Microsoft recommended relay restrictions but am still being bombed with spam relays.

Access restrictions are currently set as:
Access, Relay, Only the list below
IP 198.162.1.0 Subnet 255.255.255.0

[CHECKED] Allow all computers which successfully
authenticate ...

Queues identify the spam sender as: Postmaster@OurDomain.com

Any idea how they are getting in?

Any suggestions appreciated.

Thank you,

Jim

Make sure Allow all computers which successfully
authenticate is UNCHECKED!

Have you checked and made sure that you can not relay thru` your server. Check out this link which guides you through spamming and the restrictions on E2K.
