Server being used as a spam relay

[romanus]

One of my domains has allowed someone to send an enormous amount of spam in the past hour. How can I find out which domain is letting this unscrupulous charachter in?

whats in mail queue and Exim logs

hi,
have you found those Mails in Mail queue manager, if so you should check the header info and it should have the domain name in there.

If its through php based script then you would need to look in exim logs and find out who's the culprit and do a clean up

see ya,
