First off, make sure your mail server is not an open relay. An open relay is where a mail server will forward on email even when nither the recipient nor the sender are its local users. You'll have to read a bit on your mail server to see how to configure it properly. There are some webbased tools to test if your an open relay or not. (http://spamlinks.net/prevent-secure-relay-test.htm#web)
2nd, you should be able to setup your email server so that authentication is required to send email from it. This way the only people who can send email from your server are users who have a mail account on the server. Now, even if they forge the source address in an attempt to fool the 1st safeguard ... your server will additionaly insist they provide a username / password.
(I dont know much about linux (or mail servers honestly) so I cant really provide much more detail than that)
3rd, run a good Anti-virus sweep on all your machines. Some viruses will send mass mail with variants of your email address ... and often generate bounce messages. If its a virus, the problem may not be on your linux box but another on your lan.
4th, make sure you have a decent firewall in place
After all thats said and done you should be ok. If you're still being blocked by spam services (because of past spam) you may need to send a request to some of the spam / open relay databases saying you've taken the above steps and ask to be removed.

I seem to have a serious problem that needs some heavy duty geek

are my favorite geeks, and I don't know where else to turn :-(
The spammers have snatched up my jensimmons.com domain, and used it to
forge addresses on their emails. It's been happening for a long long
time, but in the last month, they've _really_ used my domain a LOT (I
know this because I am daily getting dozens of rejected email notices
for spam emails sent from ajdiv @ jensiimmons.com , baovzmr @
jensimmmmons.com , etc etc. All crap fake email addresses... well,
except with my name spelled right -- I'm writing it wrong here to
prevent more spam.)
The thing is, now all the email I send from jen aat jenssimmons.com is
being rejected from the big email houses. Like I just tried to send an
email to a gmail account -- rejected. I've apparently been completely
banned from gmail. The other day I sent an email to 10 addresses at one
time, including yahoo and hotmail and gmail addresses, and it bounced
from almost all of them. It's very annoying and getting scary --
basically I'm getting labeled by everyone as a spammer and I'm not a
spammer!
I have my own server (Redhat Linux) which hosts jensimmons.com among
other sites. I do not have Spam Assassin installed ('cause I don't know
how to do it / I don't know UNIX), so I get a ton of spam. I expect
that spammers are not actually running anything through my box, so I
can't block them or stop them from my end -- is this right?? Or maybe
I'm misunderstanding what is happening, and I can do something --
install something / report something....
so that's my question, what can I do to stop these spammers from
stealing my identity, and to get back to where I can email people again
at gmail / hotmail / yahoo / aol / etc??????
HELP!!
thanks,
jen
