Someone sent a spam message to a valid email address on our server. It bounced (no idea why), but more importantly, it caused ListMail to remove this address from one of the lists. Here is the message:
From: ListMail Notification
Sent: Thursday, December 15, 2005 11:37 AM
Subject: List 2: Bouncing User Removed
A user has been removed from your list: Contributor Newsletter
Their information was as follows:
Email: <snip>
First Name: Amy
Last Name: Ewart
IP Address: Unknown
Ref. URL: Manually Added
---------- The bouncing message follows ----------
<snip>
Any ideas on why/how this could happen?
