Mail not showing up in Mac mail and iphone (Sky email UK)

Hi,

This relates to a post from yesterday which I thought was solved, if only… !

If I check my mail on iphone it doesn't show up later in Mac mail. I have 5 accounts set up. 3 work fine, 2 don't. My Sky email account and a domain account that is set up for forwarding via Sky.

It seems to be a problem with Sky. This other forum suggests putting "recent" into the Mac Mail user name, doesn't help. It also mentions setting up a IMAP Sky account. I have never used IMAP, always POP. If I set up IMAP on phone can I still get POP mail on my Mac?

This other forum suggests unlocking the email account, never heard of that. Sounds dodgy?

Thanks in advance, I've spent hours going through all this!

Cheers!
