View Full Version : F9 mail

I am starting to see SPAM mail that has me as the sender. Would anyone know if this is a sendmail or dovecot problem ? Do you know if this just going to me or is it going out ?
How to stop it ?

I have received spam e-mail many times with my e-mail name and address forged on it. Nothing much can be done to stop it, and (quite frankly) it is not my problem. If you are not running a public e-mail server/service and have a simple, basic firewall in place, it's likely just generic spambot activity. Check your system logs for suspicious activity.

This is called backscatter. When you mean spam that has you as the sender, you mean you're getting mail from various servers saying no such user and it turns out that the sender is you, correct?
This is either a bug or feature of qmail servers, depending upon who you talk to. :) (DJB for example, feels it's a feature.)
I only know how to stop some of it with postfix, but perhaps if you look at the link, you can see a way to do it with sendmail.

Thanks for the info, Did not know it has a name
What I am seeing is my name as sender and spamassassin picking it up and marking it as spam.
My biggest concern is that I am sending this out to others outside my home.
I was able to look around the web and found
Have not tried it yet.

Ah good link. I should add it to my postfix page for the next time I run into a sendmail user with the issue.
