Can't send email with bellsouth account

One problem is that the incoming (POP) mail server shown in the error message appears to be incorrect. The server address should be "pop.att.yahoo.com" (with a period between "att" and "yahoo"). The incorrect mail server address may interfere with authentication of the sender's email address, which is needed before the outgoing message is sent.

The "530 authentication" message indicates your outgoing (SMTP) server likely requires "server authentication". Also, the "Port 25" message indicates your email program is currently trying to send via Port 25, with no SSL; but Ameritech/Yahoo accounts appears to use Port 465 with SSL enabled.

I would suggest you check the settings for your Ameritech email account in your email program. You may need to correct several settings. The steps to access account settings are somewhat different for various email programs (Outlook, Windows Live Mail, Thunderbird, etc.). You should be able to find guidance in the "help" section of your email program.

at first plz ping your incoming server & Outgoing server
if ping is RTO plz check network .

Incoming Server- mail.bellsouth.net
Outgoing Server- mail.bellsouth.net

well to the first person unfortunatly the bellsouth email system is not yet designed to work with the 3g network so you would have to turn that off to use bellsouth.

Also for all of you need to remember that both Yahoo and AOL email work with the IMAP stands for Internet Message Access Protocol. It is a method of accessing electronic mail or bulletin board messages that are kept on a (possibly shared) mail server. In other words, it permits a "client" email program to access remote message stores as if they were local. For example, email stored on an IMAP server can be manipulated from a desktop computer at home, a workstation at the office, and a notebook computer while traveling, without the need to transfer messages or files back and forth between these computers.

where as the bellsouth system is a POP system. what the means is that when you check your email client on either the computer or the phone it is actually pulling the mail from the bellsouth server to the respective devices and deleting the email unless you have both set to leave a copy on the bellsouth server.

and again the sending and recieving issues with bell south is due to the 3g network
