Misdirected Bounce

A misdirected bounce is an email Bounce Message^* that is sent to a user whose name was forged into the headers of the email that provoked the bounce. It is also referred to as an "unsolicited bounce" since it is sent to a user who should not have received it.

When a SpamCop user receives an unsolicited bounce and reports it, SpamCop sends out notifications to the administrator responsible for the mailserver that sent the unsolicited bounce. The text of such a notification includes:

This problem is also referred to as backscatter^*. When spammers send out spam in large numbers, even a small percentage of misdirected bounces can have a large impact on the innocent users who receive them. This is why misdirected or unsolicited bounces should be eliminated.

If your mailserver is sending "unsolicited bounces" it could get block-listed by SpamCop.

• You can configure the mailserver to stop doing this, by following directions on the SpamCop FAQ: http://spamcop.net/fom-serve/cache/329.html#bounces∞
• Another source of information regarding "unsolicited bounces" is this entry in the SpamCop FAQ: http://spamcop.net/fom-serve/cache/380.html∞
