[Justin Michael]

Hi,

I'm still having a problem with mimedefang's delete_recipient
not working with a mixed case recipient.  

sendmail 8.12.10
mimedefang 2.38

Here's my sample spam delivered via telneting to my host:

Here's the code from mimedefang-filter:

            if ($MOVESPAM && $hits >= $SAMoveScore) {
                action_add_header("X-Spam-Rec", "@Recipients");
                my ($neworig);
                my ($ok2add);
                $ok2add=0;
                foreach $neworig (@Recipients) {
                    delete_recipient(lc($neworig));
                    delete_recipient(uc($neworig));
                    delete_recipient($neworig);
                    $neworig="\<".$neworig."\>";
                    delete_recipient(lc($neworig));
                    delete_recipient(uc($neworig));
                    delete_recipient($neworig);
                    }                           # end of recipient loop
		add_recipient("spamdrop\@mydomain.net");
                }                               # end of movespam conditional

Here's the log:
