port 25 blocked due to spam
My VPS provider has blocked my Port 25 due to spam. I have gone over a few threads in these forums to try and work out what I can do to sort the issue.
It should be noted that I have had the problem before around 6 months ago. I updated all instances of wordpress that were in use on the server and everything seemend dandy, no more problems until now.

I have just updated them again and deleted the post queue. But I can see that mails are still being generated from one domain in particular. This domain in fact has not CMS in place and is currently just presenting the default sentora welcome page.

I have run clamav on my home dir and nothing was discovered.

I am running the most recent version of sentora 1.0.3.

An example of the kind of mail thats being output:

Any pointers as to how/where these are being generated?
