MailEnable Pro re-configuratio

We have a windows 2003 server running MailEnable Pro. We need someone to login to our server and tell us if the system is configured correctly. We suspect that we are not getting all the emails we would expect! Also we need to be sure our server is configured correctly so its not open to abuse by spammers and the like.

PLEASE DON'T respond to this project unless you can demonstrate significant understanding of MailEnable Pro because I will ignore you!
