Yahoo email with iPhone 5S

So, the wife and I both have a 5S and we can't get our Yahoo emails to populate in the mail center. It's not that big of a deal for me, since I rarely use my account, but it's my wife's primary email account.

So far we've tried deleting and rebuilding the account, both using the default Yahoo option and the Other option, using the following info:

Incoming Mail (IMAP) Server

Server - imap.mail.yahoo.com
Port - 993
Requires SSL - Yes
Outgoing Mail (SMTP) Server

Server - smtp.mail.yahoo.com
Port - 465 or 587
Requires SSL - Yes
Requires authentication - Yes

So far, none of these changes/options have worked. The only other option I've come across online is to DL the Yahoo mail app, but then you don't have all of your mail in the mail center. Anyone have any other suggestions?

I would suggest getting a neutral app that simply allows you to hook up any email. I am unfamiliar with the apps you have as I have only ever owned an Android.

However if you want to try one more time on the other app I set up my yahoo account it has the information below. so I would substitute my android server with

iphone or ios.imap.mail.yahoo.com
             ios.smtp.mail.yahoo.com

Caps lock was on just so it would be easier to read.
