Hi,

Could really use some thoughts on this; I can't figure
out what is happening.

I use the MAIL App that came on my iMac.
Seems to work fine.
Definitely set up for IMAP. (Comcast)

Have a iPhone 6S.
Also definitely set up as IMAP (Comcast)

I usually read my new eMails, first, on the iPhone.

If I do, Without deleting or trashing any, they do not subsequently appear on the iMac MAIL.
They are still on the iPhone.
It seems just opening them up on iPhone first, and reading, prohibits them from also appearing on the iMac,
or it deletes them from the MAIL App also (if there).

Why might this be ?

The really funny thing is that this behavior doesn't seem consistent for all messages.
Obviously, I am missing something.

Thanks,
Bob
