I've managed to install XAMPP, phpBB, but now I cannot configure Mercury at all, let alone make it play nicely with phpBB.
So I have two things I need.
1)Help configuring Mercury to work as an SMTP server, connect to the outside world, let the outside world find it, etc.
2)Make phpBB play nice with Mercury, so I can have phpBB send out emails and such.
I'm open to a new mail server as well, it just has to be portable. I want to be able to keep the entire XAMPP/phpBB/(and eventually MediaWiki) on a thumb drive that I can run anywhere.
