a short followup to my postings from yesterday, in which i wanted to
set up a /etc/valiases file to redirect the incoming message to a
*multitude* of executables (PHP, shell script, whatever).
the original incantation:
*: "| name-of-PHP-script.php"
worked fine. when i replaced it with my duplication script, it worked
fine, but emailing to that domain also produced a "local delivery
failed" error, even though the message was actually processed
to strip the situation down to its bare essentials, i wrote a
simpler shell script which simply did a pass through:
tee >(php $1) > /dev/null
and set the /etc/valiases file to:
*: "| name-of-shell-script.sh name-of-PHP-script.php"
in other words, i just added another level of complexity for testing
purposes. i still got the "local delivery failed" error, so it's
clearly something involving the way the shell invocation is being
what is it that causes that delivery error message to be generated?
am i not passing back the appropriate error code from the script? as
i said, the setup actually works, but *something* is informing the
mailer (incorrectly) that delivery did not take place, even when it
