Take me up on my free attachment filtering. This is the best attachment filter in the business: It checks inbound, outbound and internal attachments; and looks beyond many types of file extensions, delving into the actual file headers so it’s much harder to fool (in other words, you can’t rename a .exe file to a .txt file to bypass the attachment filter).

Ok, I’ll go back to normal stuff now.
