I am a total newb to mail servers and I woke up today to find that

someone is sending (what I guess is spam) I have looked it up and I am

now on blacklists and I can´t activate my server again as it just keeps

sending thousands of mails from my server. What can I do? 

1. While mercury is not running edit the mercury.ini with an ASCII editor like Notepad and and go to the [MercuryS] section and set the following.

 [MercuryS]

Relay : 0
Strict_Relay : 1

This will turn off relaying and set strict relaying.

2.   Go to the Mercury queue directory and remove all QCF/QDF files.  This will remove the spam mail ready to be sent to the outside world.  Actually removes all mail in the queue so you might lose some good mail.  If you want to go through all of the spam to find the one or two good messages just move the QCF/QDF files out of the queue directory to a temp location.

3.  Run Mercury.  It should no longer be accepting mail from the spammers, they should be bounces with an error message of we do not relay.

4.  Once you are sure you are no longer relaying spam go to all of the blacklists and go through the process of getting removed from the lists.
