I have a "custom" lookup implimented in perl which is used to set the

best way to force the message to be deferred if the lookup encounters a
problem? Returning a forced failure just means the message is delivered with
the old return_path, which is undesirable as it is likely unroutable outside
of the local system. The docs say "if it fails for another reason, delivery
is deferred". What would "another reason" be in this situation?
A non-forced string expansion failure. From the perl point of view,
returning undef causes a forced failure whereas calling die (I think) is
an unforced failure.
Interesting. Thanks for the hint Tony, that does indeed have the
desired effect. Never thought to try "die" before, since that tends to
kill the process. I guess embeded perl traps that somehow.
Thanks again
Gary
