I don't think so.

This avoids, for example, accepting mail for a domain that is in
relay_to_domains but for which no routing information is available,
and therefore helps catching configuration errors.

I am very reluctant in enabling callouts by default since this can add
significant load on the target system.

Well, not accepting messages for a domain if the domain's primary MX
is unavailable is kind of broken behavior for a secondary MX.

I am open to arguments that might convince me, but currently I think
that the default config is fine and consistent with the rest of the
config's policy. If somebody wants other behavior he/she is free to
change the configuration with an editor.

I am leaving this bug open for arguments until the end of April 2006,
and will close it if I have not been convinced until then.

Greetings
Marc
