Re: question about notifications

I am close to getting the always_bcc option working. I created an alias in
the mysql alias table that has 'autoreply' mapped to '| /path/to/myscript'.
I setup always_bcc to send messages to 'autoreply'. In the /var/log/maillog
I can see that postfix is attempting to cc the message to my alias but
rather than executing the command it is making an address of the form:

 "| /path/to/" and then trying to send it on.

 I have looked at content filters and started to look at writing a custom
MDA per
I really want this always_bcc solution to work.
 Does anyone know how to make postfix execute the command rather than treat
it as an address? I have seen examples that had "| /path/to/command" and it
looked like it was supposed to just work but those examples weren't using
mysql to store the account info.

 Thanks in advance.
