If you are unable to send e-mail from your Pocket PC phone, you may be able to use your wireless provider's outgoing mail server instead of using your ISP's outgoing mail server.

Outgoing mail settings for some of the top wireless providers are:

Cingular
SMTP server: cwmx.com
Username: your e-mail username
Password: your e-mail password

Cingular (former AT&T Wireless customers)
SMTP server: smtp.mymmode.com
Username: your e-mail username
Password: your e-mail password

Sprint
SMTP server: smtp.sprintpcs.com
Username: your SprintPCS username
Password: your SprintPCS e-mail password

Verizon
SMTP server: smtp.vzwmail.net.
Username: your 10-digit cellphone number followed by @vzwmail.net
Password: your password that you set up on the vtext.com webpage
