Spam with my address via other server

[marcelkraan]

Hello,

Someone is spamming and using my email-address as the From address.
That is not nice but now iam receiving millions of 'delivery unknown' and that makes my mailserver as a victem.

Can i do someting so others can't use my email-address (i think not?)
Can i do something the delivery unknown so my mailserver is sleeping better.

iam using postfix on fedora

You can filter the mails to somewhere else but your inbox and either delete them or save for later viewing.

If whoever is using your email address is from a civilized part of the world, then contact their ISP to get the activity stopped. You're getting the undeliverable messages, so you can review the headers to trace the email servers to the source and do a whois to track down the owner of the originating ip address.

Which are, with 99,9999% certainty, spambots and change at least daily, if not hourly. And end result: You may get couple ISPs to close the infected user's account and have wasted several hours to achieve practically nothing.

In effect, unless you want to try to report these spambots 24/7 and do nothing else in life, go ahead, but you are figthing a lost battle even then.
