[squid-users] hotmail attachment

One of your users uses hotmail on occasion. She said she started
getting denied downloading attachment a couple of months ago. I
haven't changed my squid settings in about a year or so.

I have this rule to block windows executable files...
acl deny_files url_regex -i \.exe$ \.com$ \.wmf$ \.scr$
^(\w+://)?([\w|\d|_|\.|\-|/]*?)\.exe(\?.*)?$

If I remove \.com$ it works.
acl deny_files url_regex -i \.exe$ \.wmf$ \.scr$
^(\w+://)?([\w|\d|_|\.|\-|/]*?)\.exe(\?.*)?$

Anyone know why this rule is affecting hotmail? Another user said she
could download attachments from yahoo .
