Ok, maybe I'm just doing this wrong since this is my first android phone, but I have tried adding my ISP's email to my EVO and it isn't working. It is a pop3 account and I have typed in the same information that was on my TP2 and it keeps saying it can't connect to the mail server. I am able to get to it through Outlook, so it isn't down.
Mine worked just fine, I would double check your ISP's pop info, and see if they changed anything. Also, you may have done this, but in the pop server box, mine filled in just the last part of the domain name, and I had to edit it to say pop.mydomain.com
I am having kind of the same problem, except my ISP does not require authentication for outgoing mail. When I uncheck the box and finalize the settings, the phone does not save the change. It reverts back to authentication required. Anyone know what I am doing wrong?
For those of you with this problem, I finally figured out that my problem was my ISP. They would not allow access to their outgoing server unless you were on their system. If you are having this problem, go to your Sprint account, my preference tab, change email server password. Use the SMTP user name and SMTP Server address there for your outgoing mail server. Everything works fine now.
