Where ist the "hook" for invoking spamassasin (spamd) in sendmail?

Hi,

even though I also use postfix+dovecot+pigeonhole, I have to install the following combination in a freshly installed FreeBSD 13,
which has been running stably on another server for a long time:

Sendmail+SASL2 with procmail and Spamassassin (spamd).
That system works with real system users and virtusertable

Procmail is used to evaluate the spam headers of a mail set by Spamassassin and to store the spam mail directly in a spam folder on the server side if necessary.

My problem is that I don't remember exactly how I installed and integrated the above combination at that time (several years ago).
Especially I can't find the place where it is specified that incoming EMails are first checked and tagged by spamd before they reach procmail.
procmail is called with the .forward file of the user directory for me

.forward
"|exec /usr/local/bin/procmail"

But obviously it would be possible to integrate procmail with following line in sendmail.mc too instead of using the .forward-method:
FEATURE(`local_procmail')dnl

Additional Processes:
/usr/local/bin/spamd -c -Q -d -r /var/run/spamd/spamd.pid
saslauthd -a pam
sendmail: accepting connections (sendmail)

Can someone tell me how/where to start to integrate spamd?

Thanks in advance and kind regards

Hi,

in my case it seems to be another procedure/workflow, because - like already mentioned -
.forward contains ""|exec /usr/local/bin/procmail" and when
.procmailrc is invoked, the mails are already tagged by spamassassin so that you can filter them with
:0:
* X-Spam-Status: Yes
/usr/home/spam

Personally I would go for spamass-milter with Dovecot+SIEVE, and totally dump Procmail which hasn't seen any release over 20 years.

I share your opinion and already use another solution (postfix+dovecot+pigeonhole).
But for special reasons I have to set up the sendmail+spamassassin scenario for a few weeks.

Kind regards

The answer is to define a global procmailrc (/usr/local/etc/procmailrc) in which processed mails are passed to spamc:

Example:
...
# Spamassassin
:0fw
* <400000
| /usr/local/bin/spamc
...
