What Are the SMTP Settings for Yahoo Mail?

You'll need this info to use Yahoo Mail in a separate application

If you use Yahoo Mail, you may use the service's online portal to send, receive, organize, and manage email. You're not limited to using the webmail version. You can use a separate client, such as Outlook, to send email through Yahoo's servers. One advantage of setting up email this way is that you can manage your email accounts in a single application. To set up your email client to send mail through Yahoo Mail, you'll need the SMTP settings.

What's SMTP?

SMTP stands for Simple Mail Transfer Protocol, which is a standard commonly used to send an email.

The standards for receiving email are Internet Message Access Protocol (IMAP) and Post Office Protocol, version 3 (POP3).

SMTP Server Settings for Yahoo Mail

The SMTP server settings apply to outgoing mail, so they're the same whether POP or IMAP is used for incoming email. In most cases, enter the SMTP settings in the Settings section of the client interface when you add the Yahoo account to it.

Here's the information you'll enter into the email program to send Yahoo Mail: 

Yahoo Mail SMTP server address

smtp.mail.yahoo.com

Yahoo Mail SMTP username

Your full Yahoo email address (including @yahoo.com)

Yahoo Mail SMTP password

Your Yahoo Mail password

Yahoo Mail SMTP port

465 or 587

Yahoo Mail SMTP TLS/SSL required 

yes

These settings work with most desktop, mobile, and web email programs and services. After you set up Yahoo Mail in your preferred email client, your mail and Yahoo folders appear in both locations.

Receive Email with Yahoo Mail

To download mail from Yahoo Mail to your email program, enter the Yahoo Mail IMAP or POP3 server settings, whichever is appropriate for your account.

Yahoo Mail Sending Limits

Even when Yahoo Mail is set up within another email program, there are limits on the number of emails as well as the number of recipients you can send using the service. However, Yahoo Mail does not disclose the number of messages or recipients users can send at a time as a means of enforcing their anti-spam policies.

If you reach the email service's predetermined limit, you will receive a notification. After waiting a specified amount of times (which should be explained within the sending limit notification message), you can begin sending emails again.

Creating a mailing list for groups that you email frequently could help you avoid these issues.
