Can you provide an example of the message that IMF doesn't like (exact
subject line and body)?   Send it to me offlist if you don't want it made

No joy I'm afraid, tho if I set the gateway level to 9 then they get
through, but then again so does most of the spam.

Try either of both of these:
1. Make sure the originating server's IP address is included in the trusted
network list.  (Message Delivery / General tab / Add button)
2. Establish an SPF record on a DNS server that Exchange can query, which
specifies the sending machine as representative of your domain.
and especially this:
3. Sender ID filtering tab - specific Accept
You could also try whitelisting specific words in the subject or body, as
described in the release notes for SP2, but the last time I tested that it
was clearly broken for the whitelisting part (the blacklisting worked fine).
Unfortunately, there is no way to whitelist a specific IP as "always pass".

Hi Guys
I have an application that sendssmtp mail through our exchange server. It
has been working well since it was installed but today I implemented IMF on
our Exchange 2003 SP2 server. The Domain is at 2003 level also.
The application resiides on an internal serverin the same network as
exchange, and sends emails out using a valid email address.
Every single email it sends is being picked up and blocked by IMF.
Is there anyway to whitelist this email address or the internal server's
The IMF settings are - gateway 7, junk  6
