SMTP does outgoing email !

Switch to POP3 instead of IMAP.
Here you can read what's the difference between POP3 and IMAP: Email Whats the Difference Between POP3 IMAP and Exchange

The problem is most likely that your phone is receiving email using POP3 rather then IMAP or an Exchange server. To solve this problem simply set up your email account using either the Exchange Server or IMAP option. You should note however that your email provider must support these in order for you to use them, in the event that they do not support them you have no option but to use POP3.

The address "pop-server.cfl.rr.com" appears to be a POP3 server (not Exchange or IMAP). See this help page from RoadRunner:

Well getting an email is free from many service provider. Their are many service provider like Yahoo, gmail, lycos, windows live mail etc. Again your service provider will also provide email address, but most of the time they are restricted to one email or 2 to the max

Gmail and yahoo are one of the most preffered email today. It very easy to get email account. Me personally would recommend gmail rather then Yahoo. The reason if you Gmail support both POP and IMAP account, wherein you can directly synchronize your Outlook or Outlook express to the mail server. This enables you to download, send recieve email directly to your computer, so that you dont have to login to the website to check the email. Also you can still READ email without connectint to the email.

Yahoo also support POP service but you have to pay for it. But gmail from Gmail it is free
To create new account goto
www.gmail.com

and click on 'create new account'

However if you are ready to pay for the service.
I suggest you to try, 'Apple MobileMe'

Unlike Gmail or Yahoo it provide Exchange Support, and it is the best

But for the basic use and if you are look for the free one try gmail it is the best

Hope i have answer your query

Potential causes:

• The server you specified doesn't exist (typo).
• You don't have an IMAP server running on the server you specified.
• It is not on the port you specified (it usually runs on port 143).
• You are denied access to the IMAP server.
• There is no Maildir directory for that username (will happen with Qmail MTA's).

to have this one check call your WIRELESS PROVIDER for imap settings and port number

On the AT&T Network, to unlock the LG Shine or CU720, it’s pretty simple:

• Put a AT&T or Cingular SIM in the phone; it does not have to be an active SIM
• Enter *#865625# then the 16 digit unlock code*
• Device should say: Network Lock Deactivated
• Phone may automatically reboot

*The 16 digit code can be obtained by calling AT&T Technical Support and given the representative the IMEI number. In exchange they will give you the Subsidy Unlock Code.
To obtain the IMEI number, type *#06# on your device. This is a 17 digit number and it is not the same as the unlock code, this is the IMEI number to give to AT&T Technical Support in exchange for the 16 digit Subsidy Unlock Code.

Your screen sensors are shot. Call your phone company see if they can replace or exchange the phone. If not, your going to have to buy a new one. but they SHOULD exchange it for sure. Good luck sorry your having so much trouble!

It CANbe setup to send and recieve emails from email services using the POP3 or IMAP protocols. Too quote:

VersaMail's easy account setup wizard will get your mail accounts configured in a flash. The intuitive design will make you a power user in no time. 

Get your email on your schedule. 
Stay on top of your life with Auto Sync: get business and personal email automatically downloaded to your phone based on a schedule you specify, and new mail alerts based on your preferences. The VersaMail® email client supports up to 8 email accounts, including Yahoo!, AOL, and Gmail. 

Access corporate email. 
Using built-in Microsoft Exchange ActiveSync, wirelessly sync Calendar, Contacts, and email with your company's Microsoft Exchange Server 2003 (access enabled by your IT administrator). Or, access business email using POP or IMAP and a compatible Virtual Private Network (VPN) client (sold separately).

Ok, email can be setup using a bunch of different protocols. The difference is how directly you phones data and the data on the server interact. POP and IMAP are methods for receiving email from the server, to send they use a protocol called SMTP. With POP3, email is all downloaded to your phone and saved there, with IMAP you only download the headers (...a header is like the back cover of a book). An Exchange server can do SMTP with either POP or IMAP, but when it says configure for Exchange - it means actually connecting to the mail server and integrating contacts, calendar items, email, like the Outlook client on your Windows machine. This is obviously much more server intensive and requires special permissions to do.

POP and IMAP will require the following information to work. Your login name, your password, your server, and whether the connection is secure. To find these out you can go to your coporate webmail. The user name is what you put in the user login spot, as is the password, the server will usually be either mail followed by a dot and the second half of your email address, or the web URL for the mail server...if the web access page address starts "https" then the connection is most likely secure.
