What are the names of the IMAP, POP3, and SMTP servers?

For IMAP/POP3 and SMTP, you use the same server name. It is:

mail.routing.net

Depending on the chosen use of your mailbox (IMAP or POP3) and the desired encryption type, the ports to configure in your email program are as follows:

If you’re new to email protocols, here’s a quick overview of the main terms you might encounter when setting up your account.

What is IMAP?

IMAP (Internet Message Access Protocol) is a method for accessing email on a remote server. It allows you to view and manage your messages across multiple devices because emails are stored on the server rather than downloaded locally. This means you can read, organize, or delete messages on your phone, tablet, or computer, and all changes will sync automatically. IMAP is particularly useful if you need consistent access to your email across several devices, such as checking work emails on both a laptop and smartphone.

What is POP3?

POP3 (Post Office Protocol 3) is another way to retrieve email from a server, but it works differently from IMAP. POP3 typically downloads emails to a single device and may remove them from the server, so the messages are stored locally and might not be accessible on other devices. This setup can be useful if you want to keep a permanent offline copy of your emails or have limited server storage. Still, it requires careful management if you regularly access email from multiple devices.

What is SMTP?

SMTP (Simple Mail Transfer Protocol) is used for sending emails. While IMAP and POP3 handle retrieving incoming messages, SMTP is responsible for delivering your outgoing emails to the recipient’s server. It ensures messages are properly routed and reach the intended inbox. Every email client needs SMTP configured correctly to send messages reliably, and it works alongside IMAP or POP3 to manage a complete email experience.

Choosing Between IMAP and POP3

IMAP is ideal if you access your email from multiple devices and need all messages synchronized across them. POP3 works best if you primarily use a single device for email and prefer to store messages locally. Understanding these differences helps you choose the best setup based on your workflow. For example, IMAP is perfect for someone checking emails on a laptop, tablet, and smartphone, while POP3 may suit someone who only accesses email on a home computer and wants offline copies.

Why SMTP is Important

SMTP (Simple Mail Transfer Protocol) ensures your outgoing emails are sent correctly and securely from your device to the recipient’s server. Even if you use IMAP or POP3 for receiving messages, SMTP must be configured properly to send emails. Without it, you might be able to read emails but not send them. SMTP works in the background, making email communication reliable, and is a critical component for all email programs, whether for personal or business use.
