Generate A Report of : "EHLO *.us"

HI.
Almost all of the spam that our server gets is from some looser with a .us domain.  
I want to block all of the .us on the SMTP, but need to generate a list of all of the .us EHLO's so i can pick out the valid ones and possibly white list those.
How do i generate a Report of : "EHLO *.us"

This is smarter Mail 14.x pro something.

All you can do is download the SMTP log and filter it with something like UltraEdit or some decent text editor.

Personally I don't advise EHLO blocking on a wildcard like that.  My EHLO blocks are things like:
127.0.0.1
ADMIN
localhost.localdomain
USER
YLMF-PC
... and then all my own hosted domains are all on EHLO block.  My mail server will never send SMTP mail posing as itself, to itself.

I kindof feel like that should be a built-in feature of SmarterMail, to block incoming SMTP from someone claiming to be my own domain in the EHLO string.
