problem... cannot send email from my phone
Have you check our Galaxy S3 document?
Email and Wireless Guide - Samsung Galaxy SIII
It has all of the settings for setting it up using POP/SMTP or Exchange. Let us know if you're still having any trouble and if you're getting any error messages, as this will help.
FWIW, it works with the Samsung Galaxy Ace IIx as well. I'm guessing it should work with any of Samsung's Galaxy phones.
Try setting up the account as an Exchange account, I did it that way on my brother's S3, with Exchange, everything either works, or it doesn't, and for the most part, it works.
