Thanks Hugo,
I thought I saw awhile back you mention you gave it ~64 bytes...I'll
give it a shot.
Thanks

David, I think that SMTP filter will let only the commands that are present.
If you remove a command, ISA SMTP filter will not accept an SMTP session
with this command.
Probably you removed NOOP because you receved alerts telling you that
someone exceded the maximum accepted command size configured in ISA SMTP
filter. Usually what I do in ISA deployments is to set NOOP maximum command
size to ~ 50 bytes to get rid these alerts and ISA not reject SMTP messages
from these remote hosts.
HTH.

Hi Hugo,
I'm starting to get a ton of 'ISA Server alert: An unsafe SMTP
command'
Body:
ISA Server name: ATLSRV02
NOOP
The funny thing, NOOP is diabled in the SMTP filter, do you have any ideas?

Code Red still bugs some IIS 4 Web-server operators
Code Reds I and II are still punching Web sites offline -- even those with
patched servers. IIS 4 users have found that either version of the worm can
crash patched Web servers if those systems are configured to redirect
visitors. Microsoft is reportedly working on a fix for this.
