Hello,is it somehow possible to tell postfix in which error cases the smtp_fallback_relay should be used? I'm trying to find a way to seperate real rejects from temporary errors. I want "my" postfix to use the fallback only if a reject occured and not if a temporary error (like from greylisting) happend. In the later case the mails should go to the queue and no fallback should be used.
Anyway to achieve this? Thanks for any hints and tipps
