Message could not be sent. Server rejected sender's email address

This occured repeatedly since I started using Att connection. I spent days to fix it. I removed and added account, but it's not helping.

The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was 'reshet2000@att.net'. Subject 'The Little Red Hen', Account: 'pop.att.yahoo.com', Server: 'smtp.att.yahoo.com', Protocol: SMTP, Server Response: '530 authentication required - for help go to http://help.yahoo.com/help/us/sbc/dsl/mail/pop/pop-11.html', Port: 25, Secure(SSL): No, Server Error: 530, Error Number: 0x800CCC78

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'pop.att.yahoo.com', Server: 'smtp.att.yahoo.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0F

Bounced email


In computer jargon, a bounced <a href="http://www.webopedia.com/TERM/E/e_mail.html">e-mail</a> is one that never arrives in the recipient's inbox and is sent back, or bounced back, to the sender with an error message that indicates to the sender that the e-mail was never successfully transmitted. But what happens when someone sends an e-mail out into cyberspace, and why do e-mails sometimes bounce back?<br /> When a <a href="http://www.webopedia.com/TERM/U/user.html">user</a> attempts to send an e-mail, he is telling his e-mail system to look for the <a href="http://www.webopedia.com/TERM/D/domain.html">domain</a> of the recipient (for example, webopedia.com) and the domain's mail <a href="http://www.webopedia.com/TERM/S/server.html">server</a>. Once the e-mail system makes contact with the recipient's mail server, the mail server looks at the message to determine if it will let the message pass through the server. If the recipient's server has predetermined that it is not accepting e-mails from the sender's address (for example, if it has blocked the address for <a href="http://www.webopedia.com/TERM/S/spam.html">anti-spamming</a> purposes), the server will reject the message and it will subsequently bounce back to the sender. The message will also bounce back to the server if the mail server on the recipient's end is busy and cannot handle the request at that time. When an e-mail is returned to the sender without being accepted by the recipient's mail server, this is called a <a href="http://www.webopedia.com/TERM/H/hard_bounce.html">hard bounce</a>.

The message could not be sent because the server rejected the sender's email address. The senders's email address is liz.workman@att.net


That isn't a question. It is also not something that anyone here can sort because the problem is that the server doesn't recognise the address. In other words you need to check your spelling.

The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was 'fkb@ameritech.net'. Subject '', Account: 'pop.attyahoo.com', Server:...


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.

See more on sever settings for "ameritech.net" users:

https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/61941/~/i886---at%26t,-bellsouth,-sbcglobal,-ameritech-email-settings

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.

Hello,

Might be you will have to contact your internet service provider or a admin if using in office environment.
The most common cause of this error is a restrictive (ISP) internet service provider. The ISP you're using won't allow you to use the Outgoing Mail Server (SMTP) that your email software
designates. They do this to reduce or prevent abuse; they don't want junk mailers going through their network
with masses of junk email.

Try turning off the firewall of your anti virus and operating system as well.
Thanks
