IMAP and POP seems to have changed

Unfortunately the email lookup tool does not tell you what the actual settings are on your device. It only tells you how your email will be set up on your device if you add it using the default settings. The IMAP email account that is normally added on a Mac or iPhone can also be added as a POP account.

What you are going to need to do is verify the email account on your friend's computer. If your friend has a Mac, then go to Mail > Settings > [name of account], then click the Server Settings tab. The top part of that page will identify it as POP or IMAP. Note the Host Name of the Incoming Mail Server.

If you can provide your mail provider, we may be able to offer more specific information. There is a trend for mail providers to move to the IMAP protocol, but most still offer POP as well.

You are using the correct server addresses for each account type. I don't see why the function would change on these account and Shaw still shows on their website that you can user either account type.
