Branding Quarantine notification mail and scheduling when notification goes out
It would be nice if you could extend some of the company branding to the quarantine notification email. Add in a logo and maybe some contact info for the helpdesk or whomever. Also the ability to add a link to the quarantine site so they can manage more than one message if they so choose.
Other anti spam providers allow you to schedule when the quarantine message goes out. It's nice to be able to set it to arrive in the users mailbox around the time they arrive. This way they have the latest and greatest.

The notification feature is great but it's surely a good template for a widespread phishing attack.
Aside from Custom logo and Helpdesk contact: "Hi firstname.lastname@example.org" should become "Hi FirstName LastName".
