Can't set up new android phone to my existing email

My email is with Mediacom High Speed Internet.com on my computer.

I just bought a Motorola Moto G phone thru Consumer cellular. After two one hour sessions with them, one call to AT&T and two calls to Mediacom still no success.



When using the phone set up system, the email app leads to a page with



nom d'utilisateur



Mot de passe



Serveur



Port



security type.



I checked my username and password with Mediacom, twice.



The Server comes up with ==pop.mchsi.com. Mediacom suggested I change this to mail.mediacombb.net- didn't work

POP3 is their pop --I tried that at first-no help



The Port number fills in with 110. Per Mediacom's suggestion I tried 995. No help



Security comes up with none, which is correct. I do not have a security set up other than my password. I haven't had to log on for 10 years.



One suggestions was to go out side to get a better signal. 3 bars. Have 1 and 2 inside. No help.



I have typed in username and password numerous times, being very careful to ensure all correct. Changed sever entry and port number as well. Signal always the same, couldn't open connection to server.
