Hello, I am sorry for using this site to ask this question, but I have found the best support for all questions related to Linux on this site and only this site.

My question is: Which is the best 3 Email Servers in the linux world and if possible the best ones for Windows.

I am trying to create a web server that hosts a forum using phpBB with a possible WAMP or LAMP setup. I need the Email server to work with phpBB.

If there are any Email servers that work on both platforms that would be even better. That way I can practice using it in Windows and the migrate when ever I need to.

(I know nothing about setting up an email server, so keep that in mind when telling me the ones that are the best)

Thank-you for any help you give.
