where e-mails are sent from?

[aboukouris]

Hi,

I found that my server has a lot of messages in queue that are from spammers.
In my configuration i have not to prevent mailing from user nobody.
After I enabled that, most of the spam stoped.

I think that i will not be able to send e-mail from web pages... and also I want to find out where those e-mails were sent from.

How can I?
Exim can show me who sent it? I saw the log files but are not detailed.
How can I see who was using mail service as user nobody?

Thanks,

Alexander

You can not check that which user has sent this email as user nobody but you can get the list of IPaddress who has used your mail service as user nobody. for that you could use netstat -plant command.

Thanks,
