I have been working on setting up a mail relay. I have just about everything working except for the procmail part. The configuration is as follows:

Internet -> mailrelay -> mail server
|
spamassassin server

I have spamassassin running on a seperate server and have configured spamc to connect to it.

I have this in my cf file:

MAILER(procmail)dnl
LOCAL_CONFIG
CPprocmail
LOCAL_RULESETS
LOCAL_RULE_0
R$* < @ $=w > $* $#procmail $@ /etc/mail/procmailrc $: $1<@$2.procmail.>$3
R$* < @ $=w. > $* $#procmail $@ /etc/mail/procmailrc $: $1<@$2.procmail.>$3
R$* < @ $=R > $* $#procmail $@ /etc/mail/procmailrc $: $1<@$2.procmail.>$3
R$* < @ $=R. > $* $#procmail $@ /etc/mail/procmailrc $: $1<@$2.procmail.>$3
R$* < @$* .procmail. > $* $1<@$2.>$3 Already filtered, map to original address


In my procmailrc file I have:

DROPPRIVS=yes
VERBOSE=on
LOGFILE=/var/log/procmail.log

:0fw
* < 256000
| /usr/local/bin/spamc
:0
* ^X-Spam-Status: Yes
/dev/null

:0 w
! -oi -f "$@"


My threshold for spamd is 15 at the moment for finding spam.

It looks like sendmail send the new mail off to procmal and process it: I see this in the log:

It is deleting spam Like I would expect. The problem is what it does with the good mail. It seems to try to send it back to sendmail and then I never see it again. I do see procmail jobs running where they have rewritten the address to end in .procmail, but it just sort of disappears.

Any idea on where I could be missing things?

solaris 5.8
sendmail 8.14.2
spamassassin 3.25
procmail 3.22
