Emails Not working? (registration/password renewal, etc)

[Capt. John]

Ask your host as to what they want the settings to be.

Emailed just now, anything I can check in the mean time? Sorry for asking so much of you man :/

Not really because all you can just do is look at the shiny settings, not knowing what the correct ones should be... any guidance prior to knowing what they should be would be a waste of your time.
