Spamc

Hi,




I'm configuring the spamassassin + postfix.
I´ve done the follow modifications in /etc/postfix/master.cf:


smtp inet n - n - - smtpd -o content_filter=spamd

spamd unix - n n - - pipe
user=spam argv=/usr/bin/spamc -f
-e /usr/sbin/sendmail -oi -f ${sender} ${recipient}



However, when i verify in man spamc, the option -f doesn't exist. So, I
withdraw.
I restart the postfix, but looking the logs, I've got:

(delivered via spamc to maildir)
or
(delivered maildir)



Before of the application of those new configurations, just delivered
maildir was returned to me and the messages were delivered. After the
modifications, the row of email dont stop to grow (mailq).

By what did I read, when is put the directive content_filter in master.cf, he
underwrite the content_filter of main.cf. Like this, with my modifications,
I would be calling the spamassassin to verify for virus instead of the
amavis (in my case). And that question of delivery; also by what did I
read, the spamc analyzes and marks the message and it goes over again for
the MTA.


Any idea for what I'm doing wrong?

Well, I don't know enough about postfix to help you much, but I can tell
you it's not the missing -f option.

-f has been "always on" since before 2.60. It causes spamc to run in
"safe failover" mode, and return error codes if it can't connect to
spamd. It's such a sensible behavior that it became the default behavior
and the option was removed. (if you really want, you can see mention of
it in the 2.60 docs for spamc off the spamassassin website)

I use the -f option, that is required - here is how i run my setup.

smtp inet n - n - - smtpd -o content_filter=spamd

spamd unix - n n - - pipe
flags=Rq user=spamd argv=/usr/local/bin/spamd.sh
-f ${sender} -- ${recipient}

/usr/local/bin/spamd.sh looks like this:
#! /bin/sh
/usr/local/bin/spamc | /usr/sbin/sendmail -i "$@"
