Auto-Responders and Non-Delivery Reports
Posted by Joe Rebis (Import) on 25 January 2007 09:18 PM


If you are receiving many non-delivery emails it may be that you have a Auto-Responder / Vacation Message enabled on that particular email message (POP3 Account).

An Auto-Responder / Vacation Message will reply to everything including spam. Since spammers rarely put in a valid return address, but do use a valid mail domain, the receiving mail server will bounce the message back to us. The Auto-Responder is set to send an automatic reply only once per day, per email address. However, at the volume of email that the spammers send this can be a hassle.

The recommended way to deal with this is to TEMPORARILY setup a filter rule in your email client (e.g. MS Outlook) to send these to a different folder or to delete them. Otherwise, you can do this using a Content Filter in your web based email. We DO NOT recommend leaving this rule enabled in the long term. This is because you would no longer be able to see non-delivery reports for valid email you tried to send.

Please note, this situation can also occur if you have the Catch-All option enabled on the email address (POP3 Account).
