Projects / smtp-after-popd


smtp-after-popd briefly authorizes outgoing SMTP message sending via Postfix for addresses that have recently been authorized to receive mail by either ipop3d or vm-pop3d. The timeout and all other parameters are easily adjusted. It is written in Perl and works by parsing syslogd-produced mail log files efficiently in real time, so that no modifications to ipop3d or vm-pop3d are required. It is CPU friendly and easy to modify.

    Release Notes: This version corrects a problem which could otherwise allow clever login attempts to spoof smtp-after-popd into authorizing an IP address to relay mail, even though the user does not really have a valid login on the system. The exploit is straightforward, so upgrading is strongly recommended.
