What is an incoming and outgoing server port?

What is the port number of outgoing mail server (SMTP) & incoming mail server (POP3).?

• I have tried 465 for outgoing and 995 for incoming but it's still blocking my password.

• Answer:

  We strongly recommend that you enable SSL for both POP and SMTP, as detailed in the above instructions. This will ensure that your Yahoo! ID, password and email messages are transmitted securely between your mail client and the Yahoo! servers. However, if you choose to not use SSL for SMTP, your email client will likely default the SMTP port to 25. If your ISP blocks port 25 or if you're unable to send email, then you will need to use port 587 when sending via Yahoo!'s SMTP server. To make this change, please follow the directions below: 1.From the "Tools" menu, select "Accounts" 2.Select your Yahoo! POP account and click on the "Properties" button 3.Click on the "Advanced" tab 4.Next to "Outgoing server (SMTP), change port 25 to 587 5.Click "Apply", then click "OK" and "Close" This error message can have a number of causes, among them: The ability to access Yahoo! Mail via a POP3 email client is only available to customers of Yahoo! Mail Plus. If you have not purchased the Yahoo! Mail Plus service, you will be unable to retrieve messages via an email client (such as Outlook or Outlook Express). You can determine whether or not you've purchased this service by visiting the password-protected service summary at this link. If you have Yahoo! Mail Plus, make sure you have the correct password entered in your email client. To test this, log in to your Yahoo! Mail Plus account. Enter your Yahoo! ID and password. If you receive an "Invalid Password" error, then you'll need to change your password. When you change your password, return to the email client and make the appropriate changes.
