Need a bit more information about how you are determining what is an
incoming mail.
Something like this should work (substitute your appropriate IP details):

sub is_local_sender {
	if ($RelayAddr =~ /192\.168\.1\.\d+/
		|| $RelayAddr =~ /127\.0\.0\.1/
		|| exists($SendmailMacros{'auth_authen'})) {
		return 1;
	} else {
		return 0;
	}
}

if ( !is_local_sender ) {
	# Do stuff for inbound mails
} else {
	# Do stuff for outbound/local mails
}

Add something like these lines to your .mc file and rebuild .cf file
FEATURE(`access_db', `hash -T<TMPF> /etc/mail/access')
FEATURE(blacklist_recipients)

Add relevant entries to /etc/mail/access and rebuild access database.

> Specific porn mails by reading the content of mail.
