If you're setting up an email account for the first time on your iPhone, just touch the Mail icon on the Home screen. If you're adding an additional account with version 2.x, touch the Settings icon on the Home screen, select Mail, Contacts, Calendars and select Add Account. Now select Other.

After entering in your email address and password (See setting up POP accounts in the HELM control panel), your iPhone will attempt to lookup the correct settings.

If it doesn't find them automatically, here are common email settings that you may need:

Mail server: mail.yourdomain.com

SMTP authentication is required.

SmarterMail 5 features an integrated  iPod/Blackberry email synch. Appliedi customers will benefit from this when SM5 is implemented.
