These Exim logs give me a headache, but it looks like your server acts as either an open relay or as a smarthost for another compromised server in your network. Your server is trying to deliver mail to some bad addresses on behalf of other addresses that do not appear to be yours, and when that fails, it tries to deliver bounces to those bad addresses, causing a plethora of delivery attempts, bounces, etc.

One quick example:

Code:
2009-01-18 15:39:33 [12484] 1LOYoH-0003F6-BQ ** kiw1@school.edu.ru F=<marisha@unitelco.com> R=fail_remote_domains: The mail server could not deliver mail to kiw1@school.edu.ru.  The account or domain may not exist, they may be blacklisted, or missing the proper dns entries.
Your server is sending mail on behalf of marisha@unitelco.com (I'm assuming that's not one of your users) to kiw1@school.edu.ru (not one of your users either). Since that doesn't succeed, your mailserver tries to inform marisha@unitelco.com (which doesn't succeed), etc. This spammer appears to have a preference for 'marisha'.

Anyway: find out whether your mailserver or any other server in your network acts as an open relay or an injection point for spam.

Well, I tried to relay mail through your server, and that doesn't work, so your server itself is not an open relay. Does your server act as an outgoing mail server for other servers/desktops in your LAN/network, or is there a web application on your mailserver? I see a lot of connections from localhost, so there may be a web application being abused by external parties (think of webforms, formmail, php forms, guestbooks, etc.). Though usually spam through a webserver has something like www@localhost or wwwrun@your.server.com as the sender address.

P.S.: what you need to do now is to take a good hard look at your maillogs and try to find out where these marisha@ addresses enter your mailserver (correlating with the logged SMTP connections). If they're all coming from localhost, some process on your mailserver (like a webserver) is being abused, if they're all coming from addresses in your network, another server, desktop or workstation is the source of the problems.

Note: your mailserver's spool is probably full of spam trying to get out, so the activity may not stop right away. You may have to empty all of your spooled mail in /var/spool/exim (I think).
