I was having the same problem then I decided to use a gmail account as my default account! It works perfectly! I can send photos with that account and use my yahoo email account for my incoming regular mail.

Hope this helps!

SOURCE: Outgoing email on my Iphone

Take a look at your SMTP mail settings. Settings --> Mail --> Accounts. Make sure that you have the proper outgoing (SMTP) server listed for that particular account.

The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was ''. Subject '', Account: '', Server:...

One problem is that the incoming (POP) mail server shown in the error message appears to be incorrect. The server address should be "" (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 "" users:,-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.

I am tying to set up yahoo account on thunderbird. i can send email but not receive.. i have tried changing server settings and port settings

Much more common is a sending issue. Often you have to send through your ISP server, contact them for what that server is, if you have sending issues.

I found directions for Outlook, which should be similar to Thunderbird:

Look closely at requires authentication settings....

Note: You must be a Yahoo! Mail Plus user to read Yahoo! Mail in an email reader program such as Microsoft Outlook. Click here for information about subscribing to Yahoo! Mail Plus.
To read your Yahoo! Mail Plus using Microsoft Outlook 2002 or 2003, follow these steps:
  1. From the Tools menu, select Email Accounts.
  2. Select Add a new email account and click Next.
  3. Select POP3 and click Next.
  4. Enter the following information:
    • User Information

      Your Name: Type your name as you'd like it to appear when you send an email message.

      E-Mail Address: Type your Yahoo! Mail Plus email address (for example,
    • Server Information

      Incoming mail server (POP3): Type

      Outgoing mail server (SMTP): Type
    • Login Information

      User Name: Type your Yahoo! ID (your email address without the "").

      Password: Type your Yahoo! password.
    • Select the Remember Password checkbox if you don't want Outlook to prompt you for your password each time you check your mail.
    • Do not select the Require logon using Secure Password Authentication (SPA) checkbox.
  5. Click More Settings. The Internet E-mail Settings dialog box appears.
  6. Select the Outgoing Server tab:
    • Select the My outgoing server (SMTP) requires authentication checkbox.
    • Make sure that Use same settings as my incoming mail server is selected.
  7. Click the Advanced tab:
    • Under Incoming Server (POP3), select the This server requires an encrypted connection (SSL) checkbox. The number in the Incoming Server (POP3) field usually changes automatically from 110 to 995. If it doesn't, type 995.
    • In the Outgoing Server (SMTP) field, type 465. Under Outgoing Server (SMTP), select the This server requires an encrypted connection (SSL) checkbox.
    • If you want to save your Yahoo! Mail messages on both the Yahoo! Mail server and on your computer, select the Leave a copy of messages on the server checkbox. If you want your messages to be deleted from the Yahoo! server once Outlook has downloaded them onto your computer, leave the box unchecked.

      Note: After your messages are deleted from the server, we cannot retrieve them.
  8. Click OK to close the Internet E-mail Settings dialog box.
  9. Click Finish to close the Add New E-mail Account dialog box.
  10. Click Close to close the Account Settings dialog box.
Troubleshooting tips
If you still can't send Yahoo! Mail from Outlook, you might be accessing the Internet through an ISP that is blocking the SMTP port. If this is the case, try using port 587 when sending email via Yahoo!'s SMTP server. To make this change:
  1. From the Tools menu, select Account Settings. The Account Settings dialog box appears.
  2. Select your Yahoo! Mail Plus account and click Properties. The Change E-mail Account dialog box appears.
  3. Click More Settings. The Internet E-mail Settings dialog box appears.
  4. Click the Advanced tab.
  5. In the Outgoing Server (SMTP) box, type 587.
  6. Click Apply, and then click OK to close the Internet E-mail Settings dialog box.
  7. Click Close to close the Account Settings dialog box.

Cannot connect to subscriber in China

Typically this error indicates that you are trying to send your Adhost email through Adhost’s mail server when you have not authenticated your email account to send mail. Our mail server authenticates you through your pop account. So when you check your email, our mail server authenticates your pop user and password, captures that IP that you are checking your email from, and adds that IP to our relay list. This list is flushed every 70 minutes. This means, if you try to send email after the relay list has been flushed and before you’ve attempted to check your email, you will receive this error.

How to fix the problem:

Fix #1 - reauthenticate on our server.

Remove any email from your Outbox. If you need to keep the message, you can move it to your 'Drafts' folder.
Click "Send/Receive". This will reauthenticate you.
Try resending the email.
Fix #2 - configure your email client to check for email before sending.

In Outlook, go to "Tools" and select "Email Accounts". Make sure "View or change existing e-mail accounts" is checked. Click Next.
Select your account from the list and click "Change".
Select "More Settings".
Select "Outgoing Server".
Check "My outgoing server (SMTP) requires authentication".
Select "Log on to incoming mail server before sending mail".
Click "OK", then "Next", then "Finish".

This will fix your problem

At home, have been unable to connect to Yahoo email. Here, emails sent to Yahoo email are getting a cannot send error. ----- Transcript of session follows ----- ... Deferred Warning: message still...

Please make sure that you've entered your Yahoo! Mail address as the "From" address in your email client. You won't be able to send mail if you've entered another address.

If you have the Norton AntiVirus email feature enabled, you might have to do additional configuration to use Outlook or Outlook Express. For more information, please visit the Symantec web site.

If you've tried the above steps and continue to have problems, your ISP might not allow its users to send messages with other companies' SMTP outgoing mail servers.

If you're unable to send email, try using port 587 when sending via Yahoo!'s SMTP server. Here's how to make this change in Outlook:

1.From the "Tools" menu, select "Accounts."
2.Select your Yahoo! POP account and click the "Properties" button.
3.Click the "Advanced" tab.
4.Next to "Outgoing server (SMTP"), change port 25 to 587.
5.Click "Apply." Then click "OK" and "Close." Source(s):…

Can received & read but cannot send yahoo mail from iphone

First step is try reseting the network settings. You can do this by going to settings/general/reset and reset network settings.
This will drop you off the network and reset your phone. Bringing your phone back up with current network settings.
Try sending mail. If this doesn't work, try changing your outgoing mail server.
Go into settings/mail, contacts, and calendars/(your yahoo account)/Outgoing mail server.
This will bring you to a list of mail servers, your primary server being the yahoo server with the AT&T smtp server under other.
Click on your primary yahoo server and switch this server to off. click the blue smtp arrow on the very top left. This will bring you back to the server list. go to the AT&T smtp server and turn this server on.
Go ahead and exit out either by the arrow or the home button.
Access your yahoo account see if you can send mail.

Yahoo email address will not accept my message

Are you using a mail client to send out emails? Outlook maybe? You can enable (check mark) "My server requires authentication" from your outgoing mail server settings in Outlook.

Some mailservers require this to avoid email spamming.
