User sending spam

[Orbixx]

Hi there,

Occasionally my exim mail queue will go seriously high due to an influx of emails being sent and received. I believe this is a user using his account to send spam, but I'm not sure how to find out which user is sending what email. Can somebody help me determine this?

Thanks.

The exim log will tell you a lot.

Hi,

you can see exim queue with the command: exim -bp
to view the email message headers: exim -Mvh <email_id>
