Can't send emails from Iphone unless I am connected to my home Wi-Fi

Which outgoing server and port settings are you using on your I-Phone?

Having the same problem.

And before a moderator asks the same non-helpful questions about the settings; yes I've confirmed all settings, password and user name are correct, SSL with password on port 465 using smtp.cox.net. 

Either get the user name/password incorrect error or port timed out error.

There is something in the cox servers not allowing the client to connect. 

Mike,

What version iOS are you running? There was a known issue with a recent Apple update that was fixed with the newest version. You should have 11.0.3 to fix the problem.
