did Sprint change their SMTP server/settings?

[chuque]

the way I have my e-mail set up is to imap to my mail server to retrieve mail. and the smtp server is set to smtp.sprintpcs.com This works well for sending mail, with out making the headers too strange. I only have to send one maybe 2 e-mails a week, but I noticed last week I was getting errors when I tried to send, forcing me to remote into my desktop to send an e-mail.

again my settings having changed, I believe it has worked since I installed Saridnours’ 3.5pr5 (tho honestly I can't be 100% sure on this)

am I missing something simple, or is my personal e-mail about to get a lot more complex just so I can send mail from my phone.
