The business email SMTP server requires authentication. To learn how to configure your desktop email client, please choose from the following programs:
If your program and version are not listed above, consult your program's help files for information about configuring SMTP settings.
Please make sure that you have entered your full business email address as the From address in your email client. You will not be able to send mail if you have entered another address.
Note: Yahoo limits messages sent via SMTP to 500 per day, and each message can be sent to only 100 recipients at once. If you're trying to send an email to at most 100 recipients, you will see an error telling you that some of your contacts did not receive the message. Please try resending your message but limiting your recipient list to fewer than 100.
Important note: If you have tried the above steps and continue to have problems sending mail, your Internet service provider (ISP) may not allow its users to send messages with other companies' SMTP outgoing mail servers. If you have set the Outgoing Mail (SMTP) Server field to smtp.bizmail.yahoo.com have set your client to use authenticated SMTP, and find that you can receive but cannot send messages, you may have to use your ISP's SMTP server address rather than Yahoo's.
