Outgoing Pop email won't send

[sanjsrik]

Hi,

I experienced this before and it's very strange. I have a pop account forwarded from Yahoo. I have the premium Yahoo mail so they let me do this with the following proxies:

pop: plus.pop.mail.yahoo.com
smtp: plus.smtp.mail.yahoo.com

the incoming stuff works fine, the outgoing for about 2 days has been saying that it can't send any messages out.

What is going wrong? I have tried creating a new Yahoo account.
I've tried assigning the outgoing mail server to Sprint as opposed to "The Internet"
I've tried taking off the plus at the beginning and turning off SSL required.

NOTHING has worked.

Any help would be most appreciated.
