Sebastian is mostly right - what you're getting is "backscatter" see *_http://en.wikipedia.org/wiki/Backscatter_(email)_*

But there IS something you can do about it -- especially with */mail.ru/*: and that is to properly configure your SPF and/or DomainKeys (the /former /is far easier). If you have a properly configured SPF entry for your domain (it goes in your DNS server, not necessarily your mail server), /*mail.ru*/ (which is actually one of the worlds largest ESPs (E-mail service providers)) will *reject *the message long _before _it gets to SPAM detection.

How do I know this? Because I subscribe to *DMARC *-- a method where the major ESPs send me a daily report of messages received and passed, as well as messaged rejected from my domains. (see _*http://en.wikipedia.org/wiki/DMARC*_**) I see reports from time to time from mail.ru showing rejected messages, but I never see the backscatter!

I hope this helps...

PS: I'm writing an article for the Wiki about DMARC -- I'll provide a link to the list when I'm done.

Some Spammer uses your mail as the FROM address for Spam. Not sure if you can do anything against that but I doubt it.
