Galaxy S5 Won't Connect to Email Server for POP3 or IMAP

[BrunoStyle]

I use POP3 from a rackspace webmail account. I use it on my PC and a few mobile devices.

Got a new S5 and all seems good except setting up my rackspace email.

I know all the setting are good, I can verify them with rackspace and on my other devices.

I have confirmed I have a good internet connection, both via wifi and the Vz network.

I tried setting up as IMAP instead, and the S5 also does not authenticate with the email server.

Rackspace can't help me, their settings are simple and work fine on other devices.

I've tried using my wifi and with wifi turned off.

Other mail (yahoo and gmail) both work fine.

Any good ideas?

After setting up Incoming Server it returns an error ”Unable to connect to server –ERR Authentication failed)”

I never get beyond this.

Fixed. Rackspace login matches up User Name with email address. So User Name must be the same as email address (can not be First Last, like you would want your Display Name)

i've got 2 pop3 accounts & was pleasantly surprised to enter login & password & the account was setup on each one.
