Hi All,

We are doing an upgrade on the machine that holds the postboxes
(mailenable) during the upgrade the server will need to be rebooted
which renders the boxes unreachable.
This causes a 550 error to be sent back to our spam catching server
(running MailScanner spamassassin and postfix).


That is a terrible configuration error. A host outage should
never result in 5xx mail rejects.

I don't love it either but it is how MailEnable works when it can't
access the box, it responds with -
550 5.7.1 Unable to relay for originallocalsen...@domain.co.nz (in reply
to RCPT TO command))

Don't we all love brain-dead systems.

I recently added a translation mapping for SMTP server inputs.
That was meant to map inputs from brain-dead SMTP clients into
something that satisfies basic SMTP syntax rules.

Perhaps I should also add a translation mapping for inputs from
SMTP servers, so that in the future, one could replace the above
reply by a 4xx class reply.

I dealt with a similar brain-dead relay destination by creating a never_reject transport that had soft bounce turned on.

This worked pretty well, but only because I had a valid user list from the offender.

Wouldn't that be about the same as what you describe above?
