Okay, so quick search yields that no one else has fought with this yet,
and since I'm the on that asked for the feature way back when, I guess
it is only appropriate that I'm asking for this too. :)
In short - `sendmail -bv` does not behave as expected on Postfix. I've
known this for about a year, but him-hawed about speaking up. Now it's
biting me in the rear. Instead of printing to the terminal the results,
it emails the current user the results.
I did quite a bit of research on the matter, and it has something to do
with postfix not being run as root or somesuch. Whatever the reason,
there's really no way to make `sendmail -bv` behave as it does with
sendmail.
The alternative would be to provide what I call spamass-milter -y, which
would be to bring your own expansion command. Convienently for me, I
have one handy:
tshadwick# postmap -q [email protected] /etc/postfix/virtual
tshadwick
One could, in fact ditch -x and use -y on the same system by doing this:
tshadwick# sendmail -bv [email protected] | grep "deliverable:
mailer local" | awk '/mailer local, user (.*?)/ {print $6}'
numbski
(different machines - output from both is accurate).
So I guess what I proprose is allow -y to call a single command (I could
do the above example in a script), and it would then behave as -x does
today.
The reason I believe this is important is because I have another site
running postfix where postmap -q wouldn't do the job. They are using
postfix's mysql capability. I could however structure a script to query
mysql and return the correct result. It would allow proper
customization all the way around.
For now, I guess I can recompile spamass-milter and just change the
behavior of -x, but long-term I expect more users to go from sendmail to
postfix, and the result of -x right now on postfix isn't good - it
leaves a ton of zombie processes waiting to get an answer back. Not
your fault - you wrote this for sendmail, not postfix. Personally, I
feel like the Postfix project is being somewhat obstinate about the
whole thing - lots of people rely on sendmail -bv's behavior. Simply
allowing us to throw a flag or set a variable to get the old behavior
back would be trivial, but they have repeatedly refused to do so. This
fixes that.
