Comcast SMTP Settings
If you have an account with Comcast and you want to configure your mail client to send emails, all you need to do is enter the following Comcast SMTP settings into the server configuration area of your mail client:
| Option | Description |
|---|---|
| SMTP Host: | smtp.comcast.net |
| SMTP Port: | 587 with TLS (465 if needed; use SSL if TLS isn't shown) |
| SMTP Username: | Your full mailbox address (name@domain.com) |
| SMTP Password: | Your email account password |
Xfinity / Comcast Email Server Settings For Receiving Emails
Xfinity recommends IMAP. POP3 removes messages from the server and delivers them to one device, which causes problems if you check mail on more than one phone or computer.
Comcast POP Settings
| Option | Description |
|---|---|
| POP3 Host: | pop3.comcast.net |
| POP3 Port: | 995 |
| Requires SSL: | Yes |
| POP3 Username: | Your full mailbox address (name@domain.com) |
| POP3 Password: | Your email account password |
Comcast IMAP Settings
| Option | Description |
|---|---|
| IMAP Host: | imap.comcast.net |
| IMAP Port: | 993 |
| Requires SSL: | Yes |
| IMAP Username: | Your full mailbox address (name@domain.com) |
| IMAP Password: | Your email account password |

Additional Key Points to Remember
Turn on third-party access first. Sign in to Xfinity Email, click the Gear icon, select Settings > Security, and check the box under Third Party Access Security. If it’s unchecked, your email app will show an error during setup.
💡 Note: Xfinity is moving Comcast.net mailboxes to Yahoo Mail through 2026; your address stays the same. Once you accept Yahoo’s terms and sign in at login.yahoo.com once, the Comcast servers above stop working for that mailbox. Re-add the account in your app with imap.mail.yahoo.com (port 993), pop.mail.yahoo.com (port 995), and smtp.mail.yahoo.com (port 465 or 587). If your password is rejected, generate a Yahoo app password. See our Yahoo Mail settings.
💡 Note: Customers who use a third-party email application through a POP connection are now obliged to use a secure mail server and are no longer allowed to utilize POP Port 110. The company made this change to improve the security of customers' email and Xfinity credentials and prevent them from being compromised.
POP is still supported, but your email app must use secure port 995.
The following are the general guidelines for transitioning to IMAP.
When using certain email clients, moving from POP to IMAP is as easy as inputting your Comcast email address and password. This ease of use extends to many client applications. However, if this common solution does not work, you might want to try the following steps:
- On the device, you can access your Comcast mail account, look for your email application's Settings or Preferences section.
- Select Add new (IMAP) account from the menu.
- When prompted, enter your Comcast mail address and password and hit submit.
- Now, you should separate POP and IMAP accounts from Comcast.
💡 Note: Before you delete your POP account, ensure that any emails or folders you want to save move into your new IMAP account. If you delete your POP account without doing this, you will lose them.

POP3 vs. IMAP Email Servers: How To Choose
There are two types of MAA protocols: IMAP and POP3. IMAP and POP3 are both used to retrieve messages from the mail server and send them to the recipient's device.
IMAP syncs all devices and apps linked to an email account with the server and keeps a master copy. Thus, the system will reflect any changes you make on one device across all of them if they get connected to the same mail account.
On the other side of the coin, POP3 does not provide this kind of synchronization. You can download all emails on the server to your device and choose whether or not to keep the server copy. There is no way for changes made on the device to get communicated back to the server.
In the end, IMAP is preferable to POP3 when it comes to synchronizing your email because it is the method that will save you the most time and effort.
