My user has a Google account for SMTP and a prodigy.net.mx account for POP. He is getting these hundreds of delivery status notification (failure) that contain a porn link. (Never clicked on the link but the wording is porn).
Any ideas on how I can stop this?
Here's what was in one of the emails, minus the bad language and with an xxx before any email addresses:
"Daniel Mcintyre" <email@example.com>
11/11/2014 3:48 PM
from nlpiport22.prodigy.net.mx ([22.214.171.124]) by nlpiport16.prodigy.net.mx with ESMTP; 11 Nov 2014 16:48:10 -0600
from s0106602ad090a6ee.cg.shawcable.net (HELO [192.168.243.237]) ([126.96.36.199]) by nlpiport22.prodigy.net.mx with ESMTP; 11 Nov 2014 16:48:10 -0600
He uses Thunderbird as his email client.
