That is one way to do it in Watchguard. I chose to allow almost all types of
attachments, then chose to disallow based on the extension (*.com, *.exe,
*.scr, etc.). Trust me, I wasted only a minute fraction of the time setting
that up compared to the time to write Imail rules.
To exclude .jpg in watchguard, I typed "*.jpg" and added it to my exclude
list. I did that without rebooting anything and once done, the users still
get their messages, and they know what kind of attachment was stripped from
their email - without any intervention by me.
To approximate this in Imail, I had to add this line to Rules.ima:
B~(name=".*\.jpg"\s|name=.*\.jpg\s|begin 6.*\.jpg\s):PictureBox
Then I had to stop and restart stmp, plus manage all the forwarding,
infomanager, etc. Now tell me which is easier? I am still getting false
positives on some of these rules in Imail. Trying to wade through and figure
out why it is catching emails without attachments.

Subject: RE: [IMail Forum] Watchguard port 25 behavior
IMHO the stripping on Watchguard FW is overrated. E.g. MIME encoding of an
XL file with Outlook will look like x-application-MSExcel or something but
with Eudora it will look like x-application-xls. So you end up adding new
MIME declarations all day instead of doing something productive. If you wish
to strip attachments out of emails you would be better served buying Declude
Virus and BANNING the extensions at the server. http://www.declude.com
