Configuring STMP in Gmail

Configuring STMP in Gmail

Hello, 

I have successfully forwarded my ZoHo email to my gmail address, but also want to be able to reply from gmail. When I try to set it up I keep getting this error message. " Your other email provider is responding too slowly. Please try again later, or contact the administrator of your other domain for further information."    I have tried both  port 465, SSL and port 587, TSL. My password is correct, the only thing I am uncertain if if my first name is actually my user name, and I can't seem to see any other user name in my settings on ZoHo. Please help someone!!!!!!!! Thank YOU!
