[Esa-l][OT] Attachment blocking

[Leonard L. Goldenstein]

Here is a list of sites I have blocked out with squid - They seem to be the
common sites users go to for free webmail (read: pain in the butt for
sysadmins).
mail.chek.com
mailchek.com
inbox.excite.com
email.cnn.com
mail.yahoo.com
webmail.netscape.com
hotmail.com
hotmail.msn.com
passport.com
