POP3

What is POP3?

Defined in RFC 1939, POP3 connects to the server, downloads new messages, and usually deletes them from the server afterward. The mail then lives on that one device, which makes it simple and quick, and also means that a second device does not see the same messages unless the program is set to leave copies. The newer approach is IMAP, which keeps the mail on the server and shows the same folders everywhere.

Sending mail is a separate step, done with SMTP.

How does it apply to hdiss.net email?

High Desert customer email is set up for POP3: the incoming server is pop.hdiss.net, the outgoing server is smtp.hdiss.net, and the username is the full email address. The service agreement says email is for HDISS customers only and must be downloaded to a desktop mail program. Webmail at hdissmail.hdiss.net/mail/ lets you read mail in a browser.

The company does not publish the encryption or port settings on its site. If your mail program asks for them, call 775-575-9593. Never guess at these, and never enter your password on a page you reached from an unexpected email.

What should I do about it?

Before you replace a computer or phone, copy or move your saved mail, because POP3 may have left the only copy on the old device. Read keeping email when you change devices and POP3 vs IMAP first.

Set-up steps for common programs are in Outlook, Apple Mail, iPhone and iPad, Android and Thunderbird. Some big mail apps have removed POP3 support, so check the article for yours.
