IMHO this is something you need to solve no matter what. Failure of
a local delivery program shouldn't cause lost or bounced emails;
fixing this is usually just a matter of wrapping the program in
appropriate shell magic to return the "temporary failure" error
level (75 I think). For instance, when using postfix you can just
use the following:

mailbox_command = /your/local/script || exit 75

This way, even if the script fails running for *any* reason, postfix
will just requeue your email. Again, this is not postfix-specific
at all.

Bye,
	Andrea
