Og Geez...I;ve really f@$ked this one up

Ok...so some of you may have read my last thread asbout how I'd screwed up my email by archiving it. So by now I've said screw it and put the new computer together. It rules except for the fact that it uses Windows XP. So now how am I supposed to setup my email account? I use a local server and it just ain't working. I actually had to register a new username on here just to post this since my other account is routed to my regular email. Damnit...if someone can help me out on this I'll give you my car when I die. This is driving me f*!king insane!
