MIMEDefang 2.43 is available at the download page.
Changes are:
- filter_relay, filter_sender and filter_recipient can return fifth element specifying a delay before returning a code to the SMTP client. This lets you implement tarpitting without tying up a Perl slave. However, the delay does tie up a libmilter thread.
- mimedefang.pl.in: If resending a message fails during streaming, we bounce the message and log an error at LOG_CRIT importance.
- Modified C and Perl code so that filter_relay is called when remote client connects rather than after MAIL FROM. This means the $helo argument is NOT available!
- mimedefang-multiplexor.c: Add -X option to run a “tick” request every so often. Added -Y option to set syslog label.
- mimedefang.pl.in: Call md_openlog lazily so users can call it from filter to change syslog label.
