I have a server setup to relay mail, connections are only accepted from
local network.

Mail server works well, but every once in a while it returns
2001-10-16 18:50:22 15tRnc-0008VF-00 ** XXX@??? <mailto:XXX@XXX.com> :
unrouteable mail domain "xxxx.com"

This can happen to a whole mail out or an individual message.

Sometimes sending mail from joebloggs@???
<mailto:joebloggs@remotedomain.com> to joebloggs@???
<mailto:joebloggs@remotedomain.com> gets unrouteable mail domain and the
error is successfully sent to the same address. very confusing.

It can run for 2 days without an error, and the next day can have anywhere
from 1 unroutable to 100.

dig mx domainname.com returns values, ie lookups are fine.

I have setup named on the machine to see if it helps, but it does not.

Can anybody help?
Many thanks.
