If you're having trouble with connecting your email application on your PC or Mac, before you troubleshoot any further, make sure you have the right settings in your mail program.
To configure an email client to use Comcast email (@comcast.net), the following settings should be used for sending and receiving email:
Incoming Mail Server Name:imap.comcast.net
Incoming Mail Server Port Number:
Recommended:993 with SSL ON
Only if Needed:143 with SSL ON
Outgoing Mail Server Name:smtp.comcast.net
Outgoing Mail Server Port Number:
Recommended:587 (SMTP)
Only if Needed:465 (SMTPS)
SSL Encryption:checked
Authentication:XFINITY username and password required
Using POP to retrieve email will cause a less than optimal experience, especially when you use multiple devices to check your email. We strongly recommend IMAP over POP since this will keep your emails in sync across different devices. If you do need to use POP due to any reason, you can use the following connection information:
Incoming Mail Server Name:mail.comcast.net
Incoming Mail Server Port Number:995 (POP3 With SSL)or110 (POP3 Without SSL)
NOTE: To prevent spam and to ensure the security of our network and customers, Comcast no longer supports the use of port 25 for sending email. If you use an older email client (Outlook Express, Outlook, Mac Mail, etc.), this may impact your ability to send email
