The problem with allowing access to external mail resources (HTML-based, or
otherwise) such as Yahoo and Hotmail accounts, is that they are great
avenues for completely bypassing your email server's defenses against
virus-infected attachments.  Yes, it may be company policy that client PCs
have anti-virus software and so on, but server-based defenses at the
front-door, are still desired.

In my shop, the only accounts that can access external mail sites (we block
them at the web proxy) are those of us involved in troubleshooting email
delivery problems, so that we can quickly send test messages between our
work addresses and external domains, when troubleshooting delivery problems.
That's just 5 admins out of 15,000 users.

Just a thought.
