Do you use Mozilla Thunderbird to read your Yahoo Mail?

If you are currently using non-SSL ports for POP3 (110) or IMAP (143) your settings must be updated to use the SSL ports POP3+SSL (995) and IMAP+SSL (993)

Yahoo is disabling the non-SSL versions of their services!

You must use port 995 + SSL for Yahoo POP3 access.
You must use port 993 + SSL for Yahoo IMAP access.

To change your Thunderbird from non-SSL to SSL ports please follow these directions:

First, open Thunderbird, right click on your Yahoo account, and click Settings:

Under your Yahoo account name click Server Settings.

If using IMAP change the port number to 993 and change the connection security to SSL/TLS:

If you are using POP3 the port number should be 995, and make the same SSL setting change.

You do not need to change your username, password, incoming mail server, or outgoing mail server settings when updating your incoming mail server port and SSL options.
