Yes. One needs to set:
_destination_recipient_limit = 1
However, I have not been able to make it work without altering the
spamd daemon. In particular, spamd looks for a physical account on the
server it is running:
sub handle_user_setuid_basic {
...
my ($name, $pwd, $uid, $gid, $quota, $comment, $gcos, $dir, $etc) =
getpwnam($userid);
if (!defined $uid) {
my $errmsg = spamd: handle_user unable to find user:
'$userid'\n; #die $errmsg if $spamtest-{'paranoid'};
# if we are given a username, but can't look it up, maybe name
# services are down? let's break out here to allow them to get
# 'defaults' when we are not running paranoid
info($errmsg);
return 0;
}
...
}
On our server there is a spamd user account. Therefore, I changed the
'if' section above to:
if (!defined $uid) {
($name, $pwd, $uid, $gid, $quota, $comment, $gcos, $dir, $etc) =
getpwnam(spamd);
}
At this point spamd is able to find a local account and spamc is
correctly ran with the user it is suppose to, i.e.:
spamass unix - n n - 32 pipe
user=spamd argv=/usr/local/bin/spamc -u ${recipient}
-e /usr/local/sbin/sendmail -oi -f ${sender} ${recipient}

Re: Per-User required_score
Within postfix/master.cf I have the following lines :
smtp inet n - - - - smtpd
-o content_filter=spamassassin
This pushes mail through the following lines :
spamassassin unix - n n - - pipe
user=nobody argv=/usr/bin/spamc -f -e
/usr/sbin/sendmail -oi -f ${sender} ${recipient}
Hope this is what you were after...
Thanks,

Re: Per-User required_score
Well, the problem is that if you run at MTA time, you can't really do per-user
configs.
spamc -u will work, if there's only 1 user. it won't work with multiple
users, such as when there are several recipients for a single message, unless
you can get the MTA to split the message up into multiple messages, but that
is problematic/has pros+cons assuming the MTA will even let you do it.
So in short, if you want per-user configs, switch to running SA at the MDA
(procmail, maildrop, etc.)

If you -only- need Per-User required_score you may be able to achieve
that via a two stage process.
Run SA at your MTA level but have it -only- add a specific header with the
score value. Then in your delivery process have some kind of customized
delivery agent that would look up the Per-User required_score, combine
that with the SA header score and take the specific user desired
action. (change subject header, route to 'Junk' folder, etc).
This would have the disadvantage of defeating the one main reason for
running SA at the MTA level (the ability to SMTP-REJECT spam).

Re: Per-User required_score
David,
I want to give users control of the required_score variable.
I am using Postfix // SpamAssassin // amavis.
...
spamassassin unix - n n - - pipe
user=nobody argv=/usr/bin/spamc -f -e
/usr/sbin/sendmail -oi -f ${sender} ${recipient}
If your concern is to have per-user SQL-based spam scores,
but want to keep SpamAssassin at the MTA level, and since you
are already using amavisd-new - why not let amavisd call SA
directly, and provide its SQL (or LDAP) lookups functionality.
This allows SpamAssassin to only be invoked once per message,
yet still offer individual per-recipient spam levels, individual
pass/block settings, ..., even for multi-recipient messages.
