iPhone Email Send - Time Warner Internet

This question is about "iPhone Email Send", with Time Warner Cable internet and apps. I believe there is an expired certificate on outgoing email server mobile-smtp.roadrunner.com because sending only works when I turn SSL off along with an error message related to certificate expiration. This is a POP account and I've just noticed this problem recently.

Can a moderator get this to the correct people to repair?
