I have a need for one email account to respond to every email it receives.

I know about the vacation auto responder in roundcube, but it only responds to the first mail if the subject is the same.

The email account in question is receiving 3-4 mails at once from the same sender, each with the same subject. The auto response needs to send verification that it received all parts of the message. The sender's original message is being split up because of the large attachment size. A result of the sender not receiving an auto reply is that they send it again, and again, and again .... Get the picture.

Thanks

EDIT: It does not have to be a user setting, or even available from the web interface.
