As I mailed Dean privately (where I also admitted that the tone of
my mail was unappropriate), we use callbacks to satisfy legal
requirements and enjoy the side-effect of decreased workload for SA.

Agreed. Sigh.

the next one if the callout failed and make a new callout statement
(if the previous one failed, of course). You have to find out how to
check that the callout was rejected with a temporary error.
Unfortunately, due to the local requirements the defer_ok is not an
option.
In the meantime, I got the remote siteadmin contacted who will
contact the mailadmin. I guess this will fix things and our
workaround will be filtering the rejectlog and applying some human
ressources there... :/
Kind regards,
