Remember that once you start VERPing your outgoing mail, you should

Yeah, I know. I would probably opt for 10 days, since there may be
some weird MTA's out there with a longer decay rate.
I get very few legit bounces in any case that it might be more
worthwhile to create a tarbaby defense (accept but not deliver), at
least for the moment.
I went through the blowback storm thing around the time I started using
qpsmtpd. Here's the plugin I use. It's probably not what you want to
use though.
#!/usr/bin/perl -w
sub register {
my $self = shift;
$self->register_hook('mail' => 'mail_handler');
}
sub mail_handler {
my ($self, $tran, $sender) = @_;
if ($sender->format eq "<>") {
return DENY, "Returned mail not accepted here";
}
elsif ($sender->format =~ /DAEMON/i) {
return DENY, "MAILER DAEMON mail not accepted here";
}
return DECLINED;
}
