  Important - If your ISP is not listed above, please contact your ISP to see if it requires a different SMTP sever setting instead of Yahoo's.


Our outgoing mail settings require SSL, which uses port 465.

Your ISP may be blocking port 465. Try using port 587 as an alternative.

Consult your POP client manufacturer for assistance changing your port settings.

Norton Antivirus Protection

If Norton is installed on your computer, you'll need to configure it to work with the POP client.

For help configuring Norton Antivirus, visit the Symantec website.

Additional possibilities to consider

  • Make sure you've entered your Business Mail email address as the "From" address.
  • Review our sending limits to check if you're hitting our cap.
