[Mimedefang] variables available for greylisting

[Cormack, Ken]

List,

I am needing to relocate my greylisting from filter_recipient, to filter_end
(to stop the whining from broken MTAs that choke on a 4.X.X before the DATA
phase of the SMTP dialog).  I'm wondering if the values used in building the
triplet from filter_recipient as shown below, are also available from within
filter_end.  Specifically, the recipient address, the sender address, and
the ip of the connecting host.

My filter_recipient currently looks like this:

sub filter_recipient ($$$$$$$$$) {
    my($recip, $sender, $ip, $rest_of_the_junk) = @_;
    if (greylist_whitelist($ip) || whitelist_recipemail($recip)) {
    return ("CONTINUE", "");
    }
    if (should_greylist($sender,$recip,$ip)) {
            md_syslog('warning', "Greylisted Triad:$sender:$recip:$ip");
            return("TEMPFAIL", "Tempfailed: Your server should
auto-resend");
    }
    return ("CONTINUE", "");
}

The greylist_whitelist, whitelist_recipient, and should_greylist are all
functions defined elswhere in my mimedefang-filter file, and which do the
actual work of greylisting.

Could I be so lucky as to simply set "MX_RECIPIENT_CHECK=no" in
/etc/sysconfig/mimedefang (to disable filter_recipient), and then rename my
filter)recipient to something like "sub my_greylist" and expect it to work?

Thanks for any responses.
