Using POP3 also frees up some space on your server this way.Ī disadvantage of accessing your mail using POP3 is for the time you try to do that on multiple devices. This means that you’ll be able to read your emails offline. With POP3 in mail server Windows, all the emails are downloaded from the server and stored locally on your PC or device. This is what is often called an “incoming mail server.” These are settings that you define in your email client’s settings. When you use encryption, which is highly recommended, the default for POP3 is 995. It uses port number 110 for accessing email via unencrypted POP3.

POP3 (short for Post Office Protocol 3) is a very common protocol for incoming mails, especially among mobile users. The relay will use that record and SMTP to deliver the message to the receiver. The “receiver” should, on the other hand, have configured a DNS Mail Exchanger or MX record so that senders can find them on the internet. When you push send for your email, your “Outgoing Email server” will use DNS to look up the internet address behind your recipient’s email address, and then tries to contact the receiver mail server. Receivers accept mail from relays and deliver the message into a mailbox. Relays accept emails from users and then route the messages to the recipient. SMTP servers come in two variations: relay servers and receivers. Your email client and several other Windows email servers that are involved with the task will use SMTP to route the email and direct it to the recipient’s mailbox. Simple Mail Transport Protocol or SMTP is a protocol used when you send an email. The most notable email protocols are POP3, SMTP, and IMAP. Your mail server settings will determine what protocols are used and are available for these purposes and the type of your mail client connects to the mail server. There are a few different protocols available for accessing your emails, downloading emails, and sending emails.
