I required the following to allow Hotmail and Gmail: acl Hotmail dstdomain .hotmail.com .hotmail.msn.com .login.live.com .mail.live.com .passport.com calendar.msn.com g.live.com acl Gmail dstdomain .gmail.com mail.google.com ssl.google-analytics.com acl GmailUrlRegExp url_regex -i .google.com/accounts .google.ca/accounts These were used in combination with a couple other lines to allow Gmail without allowing Google, and allowing Hotmail without allowing MSN or Microsoft sites.
