Re: (Problem) Sending Mail Error 553
Recently Yahoo found a Security Hole on their servers
Message says:
*******************************************************************************************
The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was ***********. Subject 'letter', Account: 'pop.att.yahoo.com', Server: 'smtp.att.yahoo.com', Protocol: SMTP, Server Response: '553 From: address not verified
»help.yahoo.com/l/us/yahoo/edit/a···dex.html,
Port: 25, Secure(SSL): No, Server Error: 553, Error Number: 0x800CCC78
*******************************************************************************************
How To Fix this?..
You need to verify your email address to be able to send out mails, and yahoo is no using port 25 is using port 465 through a SSL connection.. so if u have an ATT account.. your outgoing should be smtp.att.yahoo.com
ok, now you need to sign in on webmail, go to "Mail Options", Then go to Account, Click on "add or edit an account", then click on "Add",
and you'll have:
*Step 1: Enter Account Name
Please enter a name for this account. This name will only be used for display purposes.
Just type "Test", you need it just to send the verification mail, Continue
*Step 2: Enter Email Address
Name: just type your name here --------------
Email: ***type an alternate email to be able to receive the verification code,***---
Continue.
*Step 3 Setup Mail Server
You need to SKIP this step
*last step will send the verification email
ok, now sign in on your alternate email open yahoo message
, copy the verification code, lick on yahoo link, paste and verify, that basically it, worked for me.
Hopefully will work for y'all
like i said its a Yahoo security hole, not AT&T Issue, sad thing is , there is no ETR, as far as i know, yahoo is working on it. im gonna try and digg for a ETR.
If this doesn't work contact yahoo 1-408-349-1472
its either Free or fee Based
Good luck | |
| Thank you. Your steps for setting up alternate email addresses through the yahoo mail site did the trick. I can send emails again!!! | |

I too have been hit by this (or I should say my wife was). I ran through the steps and it did seem to resolve the problem. Not sure how exactly but it seems clear that the yahoo smtp server is not only validating the username and password used to login to the smtp server but it wants the from address to be a 'valid' address for the account. Seems overkill to me. | |

IT'S FOR YOUR PROTECTION! So quit yer yapping or Ma Bell will show up at your house with a nuke to protect you even more!
Seriously, overkill seems an appropriate way to put it. but I also suspect that the implementation was botched too. Why didn't they send out an email to everyone? Why is the verification area of the webmail options interface so deep in the system and hard to find?
It's all well and good to try and tighten up the network, but it often helps if one bothers to inform the end users.
