One of my web sites is no longer able to send e-mail from the mail-users function to a specific domain. The e-mail is rejected with this message:
I'm afraid I wasn't able to deliver your message
to the following addresses.
This is a permanent error; I've given up.
Sorry it didn't work out.
(address and IP info) failed after I sent the message.
Remote host said: 550 5.5.0 Mail rejected for container policy reasons.
Obviously this is some setting on the receiving server. The domain email administrator won't explain why the email is rejected.
Anyone else seen this message? Anyone have any ideas on what I could change in Geeklog to fix this?
Not only can I not send e-mail to registered users on that domain, but I expect no one on that domain will be able to register since I will be unable to send the registration email to them.
