Palm Treo 755P User Manual page 313

Some email service providers have other requirements specific to their service. For
example, Yahoo! requires you to pay for a POP account in order to download email
messages from your Yahoo! account to your device. Check with your service provider to
see if any provider-specific requirements exist.
Service provider settings change frequently. If your email account was working but you
are currently experiencing problems, check with your wireless or email service provider
to see if any of the account settings have changed.
I Have Problems Sending and Receiving Email
Short periods of time when email is unavailable are common due to server problems or
poor wireless coverage. If you have problems sending or receiving mail for an extended
period of time, check with your ISP or email service provider to verify that the service is
working properly, and check with Sprint Customer Service for outage information in your
area.
Push or Auto Sync Is Not Working
If server push or an Auto Sync operation is occurring and you turn your device's phone off or
the connection to your email service provider is disconnected, the push or Auto Sync
operation fails. If push or a scheduled Auto Sync doesn't take place or starts but does not
finish, make sure your device's phone is on and that your data connection to your mail
server or email service provider has not been interrupted.
I Have Problems Sending Email
If you are able to receive email messages but cannot send them, try these steps, in turn:
Make sure your ISP or email provider allows you to access email on a wireless device.
Several providers, like Hotmail, do not offer this option at all; other providers require an
upgrade to access email on a wireless device.
Turn on ESMTP. Many services require authenticated access, or ESMTP, to use their SMTP
servers. See the User Guide for the VersaMail Application at
www.palm.com/mypalm/755psprint for information on turning ESMTP on.
