Did you setup your email account correctly?
Incoming Mail (POP3) Server: pop.mail.yahoo.com
Outgoing Mail (SMTP) Server: smtp.mail.yahoo.com
(use authentication, optionally use port 587)
Account Name/Login Name: your Yahoo! Mail ID (your email address without the "@yahoo.com")
Email Address: your Yahoo! Mail address (e.g. firstname.lastname@example.org)
Password: your Yahoo! Mail password
Please note that if your client does not support SMTP authentication, you will not be able to use it to access your Yahoo! Mail messages.
Make sure that you change the port numbers. Using Thunderbird with the wrong port numbers will cause it not to function.
Hope this helps.
Can't reply to email messages
Thunderbird 1.5 downloads my messages from Yahoo Mail Plus
I've asked for help in the Mozilla Forums, and they want me to post my preferences in Thunderbird. Where can I find them? If you can guide me to that, then I can go back and tell them what they need.
BTW, this forum has advantages of the Mozilla Forums. I like the bios on the moderators, and like the capacity to report offensive posts.
Do you notify me when I have an answer to my question?
Thanks in advance.
