Hi,
I happen to use apache james for
testing in one of my earlier projects.
It is really cool and the instructions are very easy and simple.
You should'nt have problem running it.
Also you can use other trial version mailservers from net but I forgot their name
But James is really kool and does support task like multilingual mails ect which I had problems with other trial versions.
James is free and fully functional and cannot be any better.
