Email Setup: Port Numbers and POP vs. IMAP
When you're setting up your email account, your program will ask for some information about email "protocols." Here are a couple of things to know as part of your set-up: Port Numbers:Your email port is how email moves from one email server to another. To protect your security and help prevent spam, we no longer support port 25. If you're using an older email program like Outlook Express, Outlook, or Mac Mail, you may have trouble sending email.Learn more about port 25. POP vs. IMAP:POP (Post Office Protocol) and IMAP (Internet Message Access Protocol) are two different ways to get email in your email program.We recommend using IMAPfor your Comcast email. POP can cause problems when checking your mail from more than one phone or computer because POP removes the mail from our server and delivers it to your device. IMAP makes it easier to sync your email on multiple devices because your folders and mail remain on our server until you move or delete them with your device. With IMAP, the email changes you make on one device, like your smartphone, are reflected on your other devices, like your laptop.
But if you'd still like to use POP, use these settings in your email program:
Incoming Mail Server Name:pop3.comcast.net
Incoming Mail Server Port Number:995 (POP3 with SSL)
Incoming Mail Server Port 110 is no longer supported. Make sure to use port 995 instead. You can check this in your email program'sSettings,Advanced SettingsorPreferencesmenu.
Choosing either POP or IMAP can impact the way you access and manage your email.
What are IMAP and POP?
IMAP (Internet Message Access Protocol) is a popular protocol that keeps your email on the server and always synchronized across your devices. For example, if you delete, send or mark a message as unread on one device, it is reflected on all your devices.
POP (Post Office Protocol) downloads your email onto your device. Therefore, actions on one device are not reflected on other devices. Using the same example, if you delete, send or mark a message as unread on one device, the changes will not be reflected on other devices. Sometimes, POP will download your email but not leave a copy on the server for other applications or devices.
IMAP is generally favored by those who check their email on multiple devices since it provides a more consistent experience.
General Instructions for Switching to IMAP
For some email applications, switching from POP to IMAP is as simple as entering your Comcast email address and password.
Find your email application'sSettingsorPreferencessection on the device that you use to access your Comcast email account.
Choose the option toAdd new (IMAP) account...
