I have a linux server with a mail server running on it.
I am using Plesk 8.0.1 to manage my server but also have shell access to it.
I am running a PHP/MtSql application on that server.
Recently the mail server started making problems and the php application has been unable to send out emails.
When I check the mail queue in plesk I see tons of spam emails in there.
I am not very familiar with mail server management so I am wondering what I can do to get to the bottom of the issue.
