map.comcast.net doesn't support password authentication

I am getting the above error when trying to set up my new Comcast email on iPhone, it says to check account settings and try again. I am following their directions and I get this every time. Anyone know how to fix?

Try this:


Incoming Mail Server

Host Name: imap.comcast.net

User Name: the first part of your email address before the "at"

Password: you should know that


Outgoing Mail Server:

SMTP: smtp.comcast.net. Tap on this to get to those settings>on this page it should be the Primary Server, tap on smtp.comcast.net again.

The Host Name is the same, smtp.comcast.net

User Name: same as the incoming

Password: same as incoming

Use SSL: turn this switch on

Authentication: Password

Server Port 587


Go back to the first page with the Incoming Mail Server


Tap on Advanced:

Mailbox Behaviors

Move Discarded Messages Into

Deleted Messages

Set all of these to your desired setting


Use SSL: turn on

Authentication: Password

IMAP Patch Prefix /

Server Port 993


You would be setting up the account manually. Usually it should verify automatically if you put in your email address and password.
