If you execute program from the command line, your shell process
invokes the program.

If invoked from Postfix, Postfix will prepend $local_command_shell
to the command. That should be either empty, or something that
Postfix can append the command to as a single argument.

I can reproduce this error message with:

$ /bin/bash /usr/bin/procmail

This suggests that you have:

/etc/postfix/main.cf:
local_command_shell = /bin/bash

The proper syntax is for command execution with bash is:

/etc/postfix/main.cf:
local_command_shell = /bin/bash -c

(as the manpage example suggests with its smrsh example).

AHA, now we're cooking. This actually works perfectly!!!
THis should be suggested for /bin//bash as well in the documentation.

Thanks Wietse, I knew you would give the answer!!!
