I am not hapy about my users receiving certain attachments. What I want to do is block the following (1) Attachments bigger than a certain size (2) Attachment of a certain type (mine type?). For example I would like to block .exe files. I would like to do both elegantly. If I block a message, I want to send a message to both the sender and recipient telling them what has happened. Even better I would like to send on the original message without the attachment. Anybody point me in the right direction. PS. I use vpopmail, sqwebmail etc... All virtual domains and users, no local.
