Random Unexplained Email issue

[dgent]

Our company has lots of different email addresses @ different domain names, but if I use a particular one, with any of our employees names at the beginning, and get them to register an account on our Zencart stores, or try to send an email to them via the admin, we instantly get an 'PHP Email Line feed error - check email settings'

Email works fine to this email account via traditional means, but if sent via a PHP system, instant failure.

Any ideas? Obviously its not a problem with Zencart, its an issue with this email/domain, but how does the PHP/Zencart know there is a problem, and so instantly. Its not like its even sent, and then brings back an error. Its instantaneous.

Zen Cart will be receiving a message back from the mailserver which is where the rejection is happening.
You'll need to sort out the email problem with whoever manages the mailserver settings on the webserver.

You might find some relief as far as messages from within ZC are concerned if you change Zen Cart to use SMTPAUTH as the Email Transport method and supply SMTP user/password/host/port/etc settings.

Hi

Yes, thats what I thought, I was just wondering 'what' kind of problem it could be and why it only relates to emails sent via PHP and works fine via traditional means.
