Why do "bounces" go to the wrong address when I use Sendmail?
When your script sends messages using Sendmail, the script can specify the "bounce" address (also called the "envelope sender" or "Return-Path" address). If you don't specify a bounce address, the bounce address will default to a special address that forwards to the administrative contact address we have on file for your account.
To specify a bounce address, use the "
-f" option when running Sendmail, like this:
/usr/sbin/sendmail -f 'firstname.lastname@example.org'
The address must end with your domain name to be accepted by our mail servers.
You can test your script by sending yourself a message and looking at the full headers of the message: the bounce address will be shown in a line marked "
Return-Path:". If you're not sure how to change your script to use the correct bounce address, you should contact the author of the script for assistance.
