  • Fluffy the SMTPGuardDog version 1.4 released

    Fluffy the SMTPGuardDog works as a proxy SMTP Server to reduce viruses and spam coming in to an existing SMTP server. The major improvements in version 1.5 are the ability to weight different DNSBL lists and control message handling based on a total weighted score, significant speed improvements in the processing of messages.

    You can download the latest version from
    http://sourceforge.net/project/showfiles.php?group_id=75935
    and read the documentation and other project information on our project page at
    http://www.fluffy.codeworks.gen.nz

    Other changes include detection of spammers getting inadvertently tar pitted while being validated, the option to send log files to multiple syslog devices, the ability to control the detail of debug level logging, right click menu on the display console to freeze the display, and to copy display log text, general GUI and colour improvements, and the separation of active and inactive DNSBL lists.

  • Fluffy the SMTPGuardDog version 1.1 released

    Fluffy the SMTPGuardDog works as a proxy SMTP Server to reduce viruses and spam coming in to an existing SMTP server. The major improvements in version 1.1 are the ability to specify whether each DNSBL is to be used to block or to warn only and a monitoring option so you can get a report if an IP or domain name is listed on a DNSBL

    You can download the latest version from
    http://sourceforge.net/project/showfiles.php?group_id=75935
    and read the documentation and other project information on our project page at
    http://www.fluffy.codeworks.gen.nz

    Other changes include parsing subject lines using character set encodings for matching against blacklisted header contents, a global option to log actions only, in addition to block or warn (applies to DNSBL and spam traps only), a sanity check so we only use DNSBL that appear to be working correctly (don't use ones that reject everybody), explictly deny support for BDAT/CHUNKING and XEXCH50 until these are supported, explicit recognition and handling of all known extended SMTP commands, an option to log IP addresses we consider valid and invalid, suitable for submitting to spam monitoring services, and bug fixes detailed in the change log.

  • URGENT: REMOVE *.OSIRUSOFT.COM from DNSBL lists

    You should remove or disable all references to OSIRUSOFT.COM in your DNSBL lists.

    relays.osirusoft.com is a default entry in Fluffy.

    Osirusoft.com has shut up shop, and is currently sending a negative ('junk mail warning') message for ALL email senders. So if you are using this DNSBL, anything not in your whitelist and not cached, will be rejected as junk mail.

    I will work on a method of detecting an aberrant DNSBL in the next version of Fluffy.

  • DNSRBL change recommended

    Fluffy comes with a default DNSRBL list. This listing includes dnsbl.sorbs.net. If you are using this DNSRBL I recommend editing the entry for dnsbl.sorbs.net to ignore the response code 127.0.0.10 ; this code is supposed to identify dial-up connections but I have found it unreliable in this area and liable to block legitimate email.
