Alberto Bertogli 14c48153aa smtpsrv: If the hook exits with code 20, it's a permanent failure ...

It is can be convenient for hooks to indicate that an error is
permanent; for example if the anti-virus found something.

This patch makes it so that if the hook exits with code 20, then it's
considered permanent. Otherwise it is considered transient, to help
prevent accidental errors cause final delivery issues.
