One email account shows up on Mac but not iPhone

Yes, the account is listed in Settings>Mail>Accounts, and Mail is turned on, which is why I am puzzled. No incoming mail on this account shows up in Mail on the phone, though incoming mail for that account shows up on my iMac.

This stalls out in the verification stage. But I think it's a connection problem at my location today. Will try this again later and tomorrow if necessary and will post when I have a result. Delete and add it back does sound like it should work. Thanks.

My connection finally returned, and lo and behold, the email account is now readable in both places. Thanks again.
