This document provides information on troubleshooting different POP and SMTP issues one may experience such as:

• POP isn't working
• Not receiving messages in Outlook, Thunderbird, or another email client
• Messages won't send from my email client

Please note: this feature is available only to Mail Plus subscribers. For more information on Mail Plus, please visit this webpage.

There are a number of factors that could cause difficulties with POP and SMTP access, and you'll find most of them outlined below.

I. Activate POP Access

Please ensure that you have selected the option for POP access on the Mail Delivery Status page. To check this:

1. Log in to Yahoo! Mail on the Web.
2. Click the Options link and choose Mail Options.
3. Click the POP & Forwarding on the left.
4. In the new window, click the radio button beside Access Yahoo! Mail via POP. (In Mail Classic, the text says Allow your Yahoo! Mail to be POPed.)
5. Click Save in the upper right corner to save your changes. (In Mail Classic, click Save Changes.)

II. Check settings

• Incoming Mail (POP3) Server: pop.mail.yahoo.com (port 995 SSL)
• Outgoing (SMTP) Server: smtp.mail.yahoo.com (port 465 SSL)
• Account Name/Login Name: Your Yahoo! Mail name in lowercase (your address without the "@yahoo.com").

Please note: If you have a ymail.com or a rocketmail.com account your login name is your FULL email address (e.g., johndoe@ymail.com or johndoe@rocketmail.com)

III. Check that your password hasn't changed

Log in to Yahoo! Mail on the web. If you have problems logging in to your Web-based account, try our password reset wizard.

IV. Problems sending messages

Please ensure that you have configured your email client to authenticate during the SMTP session. For more information, please visit this help page.

If you've double-checked the items above but continue to have problems sending messages, it is very likely that your ISP may block connections to external outgoing mail servers. To clarify this, please ask your ISP whether they allow users to send mail from SMTP servers that are not on their network. If not, you will need to enter your ISP's outgoing mail server in place of Yahoo!'s outgoing mail server in your email client.

V. Problems retrieving messages.

Corrupt messages within your Yahoo! Mail account can prevent successful pop sessions to occur within your email client. If there is a damaged message in your mailbox, we suggest that you log into your Yahoo! Mail account via the Web and move the contents of your Inbox to a different folder.

You can do this by following the instructions below:

The newest version of Yahoo! Mail:

1. Add a new personal folder by clicking the + button next to Folders on the left.
2. Enter a new name for your folder.
3. Click OK.
4. Return to your Inbox by clicking the Inbox tab.
5. Select the messages you would like to move by checking the boxes to the the left of them in the inbox list.
6. Click the folder button (  ) from the toolbar across the top of your inbox.
7. Select the destination folder from the pull-down menu.
8. The messages will be transferred to the new folder.

Yahoo! Mail Classic:

1. Add a new personal folder by clicking the Add link next to My folders.
2. In the window which pops up enter a new folder name.
3. Click OK.
4. Return to your Inbox by clicking the Inbox link within your folder list.
5. Scroll to the bottom of the page and check the Check all box.
6. Click the Move button.
7. Select the destination folder from the pull-down menu.
8. The messages will be transferred at once.

Once this is done, please sign out of your account and return to your email client and proceed to POP your mail.

After this step, return to your Mail account and proceed with moving the messages back to your Inbox in small increments, until you find your corrupt message and can delete it.

If you've double-checked the items above but continue to have problems receiving messages, your difficulty is most likely caused by issues specific to your local network. If you connect to the Internet using a LAN with a proxy server or a firewall, you may need special settings to access external mail servers. For further information, please contact your LAN administrator.
