Is there a way to identify "bad" html attachments from the html attachments that secure sites like proofpoint and cisco ironport sends out?

Did you mean to block all html attachments or just the bad(virus?) html attachments?

Best regards

I would like to block all html attachments except the one's that come from secure sites.

True, but we receive a lot of email from other companies that use secure mail to send documents.  Almost all of these secure mail appliances/servers send out an .htm document to click on in order to access the site to download the document.  I currently have a rule in place that blocks all .htm/.html attachments.  I do have a "white list" of senders that are allowed to send .htm/.html documents but I really don't want to maintain this list and didn't know if there was a something different with these types of .htm/.html attachments since they are coming from a "secure" source.

My apologies Marty, I totally missed that you were talking about Email Security, not Web Security.  Please disregard my above post.
