Hmmm - not seeing that here -YET. As far as I'm aware all the SPAM with giff
attachments we get have either a url or mail to link. Havn't had any reports
of an increase in SPAM getting through the filters. May have to have a look
through the 8000+ SPAM messages curently blocked to see if there are any with
this format - and to check how they are getting detected.

I'm not able to find any hyperlinks in the email. I can't click on the picture
or anywhere else that I've found. I viewed the html code in the email and this
is all that is there:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META content="MSHTML 6.00.2600.0000" name=GENERATOR>
<STYLE></STYLE>
</HEAD>
<BODY bgColor=#ffffff>
<DIV><FONT face=Arial size=2><IMG alt="" hspace=0
src="cid:001c01c66446$3573aee0$7aa4e248@umu"; align=baseline
border=0></FONT></DIV>

The giff (or other image) is inbedded within the e-mail (as displayed to the
user) with html code. If a recipeint clicks anyware on the image it usually
trys to open a url (sometimes it uses a Mail to: link instead). While no
system can catch EVERY spam we are finding the software we are using IS
catching better than 95% of spam with VERY few false positives. In our case
simply stripping the image from inbound messages is NOT an option - firstly
because we do receive a significant number image files as part of the work we
do and secondly our staff would moan like heck if they still got hundreds of
"blank" spam mail. BTW - what happens if a user clicks on the "white space"
of one of the messages you have stripped the giff out of - does it still try yo
open the url?
