Email accounts authentication required?

[bbrendon]

Required email authentication on an SMTP client? I've never heard of such a thing. My server system doesn't have authentication. Can it be optional?

Code:

Got an unknown response to the authentication process (503 - 5.5.1 Error: authentication not enabled)

Alternatively I'll request proper authentication per this error:

Code:

Got an unknown response to the authentication process (530 - 5.7.0 Must issue a STARTTLS command first. wm3sm15717280pbc.4 - gsmtp)

LOL. I feel like this is a trick. It doesn't work with or without authentication. Ummm....
