It appears spammers have been using various addresses from this domain (timt.net) in their forged "from" headers.
I've received bounce messages from some places that indicate that various fake email addresses at timt.net are being used in forged headers. So far I've seen "julie", "george", "mary", "linda", and "dan".
If you have received email from any of these "people" please be aware that I am just as much a victim of the spammers as you. The email did not originate from my site, but I get to see the bounce messages from all over. The email addresses they are using don't even exist! In an infinite universe, spammers are a waste of space!
