Can't send e-mail

[lightman02]

I just upgraded from the Touch Diamond using Energy ROM on it. When I would send mail using my ISP's server's and putting my authentication in for sending it would work just fine. However I now have the Touch Pro 2 and it will not work, keeps saying to check user name and password when trying to send. So what I'm wondering if there is some kind of registery setting or hack that allowed this to work on my Touch Diamond running the Energy Rom?? Anyone else had an issue like this??
