As older postfix installations have a "fallback_relay" variable and
newer installations have a "smtp_fallback_relay", i wanted to use
postconf to check, which version is supported.
Usally, i would expect a program to return with a non-zero exit-code at
such a failure:
r...@localhost# postconf fallback_relay
postconf: warning: fallback_relay: unknown parameter
r...@localhost## echo $?
0
So, any chance of getting a non-zero return code for errors like
"unknown parameter"?
Would be great for scripting ...
