Hi!
I have an open ticket on this, but I'm not sure that the support team fully understand the problem, so I thought I'd post for any ideas as to what could be wrong:
1. I create a subdomain.
2. I create an mailbox for that subdomain
3. I set the default mailbox for the subdomain to the single mailbox I just created.
4. I can log in to the mailbox and send messages with no problem.
5. Whenever I send a message to the subdomain address - either directly using the correct address, or by using test@sub.domain.co.uk I get an error message:
Remote host said: 503 This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server.
Or at least I did this morning - this afternoon the emails just never get delivered.
It's not an client authentication problem, since I can send successfully to the main domain addresses from the same client. What am I missing here?
But, as I said, this is the only address that fails in this way. Mail sent to the main domain always gets through.
Even if I send it from an address on the main domain, through webmail, through Thunderbird, it never arrives.
Yay!
Support just sent me a couple of test messages through the problem account, and I did the same. They just recreated the sub-domain and it fxed it! The domain wasn't resolving properly. All is well!

Sometimes it is a error in setup like here - you get this all the time with things like scripts and a simple reinstall can be sometimes all it needs .
