COMCAST.NET Email Server Settings – IMAP and SMTP

First time looking to use your Comcast email account? Well, the web-based Xfinity Connect page and mobile application are always available for the users to make use of for accessing your account. However, if you also wish to access your Comcast email account through an email program, you will need the IMAP and SMTP settings to easily configure your Comcast email account on an email program. No matter whether you wish to access your Comcast email account through Outlook, Mozilla Thunderbird, Mac Mail, iPhone, Android, or Windows 10, you will need to the following Comcast.Net email server settings (IMAP and SMTP) for the configuration process.

Email Settings Required for Configuration of Comcast.Net Email Account on an Email Account

When you are prompted by your email client to configure your email account, you will need to use these settings:

  • Incoming Mail Server Name:comcast.net
  • Incoming Mail Server Port Number: 993 with SSL ON
  • If the Mail Client lets you select an authentication method, choose STARTTLS.
    • If Needed: 143 with SSL ON
  • Outgoing Mail Server Name:comcast.net
  • Outgoing Mail Server Port Number: 587 (SMTP)
    • If Needed: 465 (SMTPS)
  • Encryption: TLS (use SSL if TLS isn’t shown.)
  • Authentication: Type in your Comcast username and password


When setting up your Comcast email account, your email program may prompt for certain information about email “protocols”. To make the configuration process easier, below are a couple of things that you may want to get familiar with:

Port Numbers: The role of Port Numbers helps in knowing how email moves from one email server to another. In order to protect your security and keep spam at bay, 25 Port Number is no longer supported. In case you are using an older email program such Outlook Express, Mac Mail, or Outlook, you may experience issue sending an email.

POP vs IMAP: IMAP (Internet Message Access Protocol) and POP (Post Office Protocol) are two mediums to get an email in your email program. Though you can use either of the mediums to get an email, it is suggested to configure your email account using IMAP. This is recommended more because POP is known for causing problems when checking your email from more than one phone or computer as it removes the email from the server and delivers it to your device. On the other hand, with IMAP, the email changes you make on one device such as your smartphone gets reflected on your other devices such as your computer or laptop.

However, if still, you wish to use POP protocol for the configuration process, it is suggested to use the following settings in your email program.

  • Incoming Mail Server Name:comcast.net
  • Incoming Mail Server Port Number: 995 (POP3 with SSL)
    • Incoming Mail Server Port 110 is not supported any longer. Make sure to use port 995 instead. You can check this in your email program’s Settings, Advanced Settings or Preferences menu.

So, these are the Comcast.net Email Server Settings (IMAP and SMTP) that you will need to configure your Comcast email account on an email client.
