I just upgraded from a Galaxy S4 to an S7 and can't get my verizon/yahoo email set up.
It uses yahoo.com so as far as I know the server settings are
incoming.yahoo.verizon.net
outgoing.yahoo.verizon.net
these are the server settings on my computer in Outlook and works.
For some reason, using the same setting in the Samsung email app doesn't work
Using POP3
SSL
incoming port 995
outgoing port 465
"Authentication required before sending emails" is checked
error message: "A security connection error has occured"
