I have a business email I'm setting up. What is a Outgoing server SMTP?

When you set up an email client, you'll be asked for "Incoming mail (POP3)" and "Outgoing mail (SMTP)." The POP3 server is the one to which your client connects to receive your incoming mail. The SMTP server is the one to which your client connects to send your outgoing mail.





In many cases, the server names are the same. Sometimes, especially when the SMTP server requires a password and/or secure authentication, separate servers are used, like for Penn State:





Incoming server: email.psu.edu


Outgoing server: authsmtp.psu.edu





If you're setting up an email client, and you've only been given one email server address, then likely it's the same address for both incoming (POP3) and outgoing (SMTP).
