I have tried to research the website for settings on my Evo and the following is the best I've been able to come up with:

Protocol - POP
Email address - name@company.com
username - name@company.com
password - *******
pop server - mail.company.com
security type - none
server port - 110

This is the only setting that I've been able to use to receive e-mails on my phone, Ive tried everything. The problem is that I haven't found the correct settings to send e-mails from my phone. When I try "exchange", I get an error about wrong username or password even though I enter them correctly.
