Hi all,
Setup is: we have a server that does the spam checking running
MailScanner / Spamassassin and of course postfix
Mail is then delivered to a machine running MailEnable (where the boxes
are held)
We had a situation where the MailEnable machine went down
*In the maillog of the server running postfix were:*

Neither the original recipient or the original sender received
notification that there was a problem or any form of bounce message. The
original recipient also never received the email.
Indeed. The original message was rejected with a permanent error
("550 5.7.1 Unable to relay"), as was the non-delivery notification.
My question is what happened to the email and the bounces and how can I
change the setup so that if this occured in the future (i.e. the spam
checking server can't communicate with the mailenable server) mail does
not disappear.
Configure the Mailenable system such that it doesn't reject mail
with a PERMANENT error for conditions that you don't consider
permanent.
You can configure the Postfix SMTP client to pretend that permanent
errors aren't permanent, but that introduces other risks.

I heard back from MailEnable and it occurs when MailEnable can't access
the boxes. This is ok and probably as it should be.
When you say I can configure Postfix SMTP client to pretend that
permanent errors aren't permanent is this something I could change
temporarily (say for the time the MailEnable machine is rebooting) and
then change back?
