Hi, On our postfix server we use: relayhost = [server1.tld]:587
How can i tell postfix to relay mails localy if server1.tld is down? I thought this should be possible with "smtp_fallback_relay"; smtp_fallback_relay = [localhost] but then i see a "deferred (mail for localhost loops back to myself)" in log. Is it even possible what i want to achieve? kind regards, Georg
