Postfix now supports SURBL checking via milter-link
by Jeff Chan 23 Jul '06

23 Jul '06

Anthony Howe has upgraded his milters to work with Postfix 2.3 and its new Sendmail 8 milter support. This means that Postfix can now filter based on SURBL hits using milter-link: http://www.snertsoft.com/sendmail/milter-link/ In addition he reports: "Also in this update, milter-link/0.3 has been updated to support aggregate list bit masks and added a new option policy-links."

Don't use compression on rsync
by Jeff Chan 10 Jul '06

10 Jul '06

Please don't use compression (-z) when rsyncing any zone files, whether the files are already compressed or not. Compression slows down the process since it uses significant CPU on both sides. And it certainly would not make sense to try to compress the already compressed files. There would be no significant file size savings, and the CPU usage would be significant. For rsyncing the uncompressed files, the amount of data transferred is usually very small since only a few records change (if any) at any given time, so again compression just adds unnecessary overhead. Therefore please don't use the rsync compression option. Thank you, Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

gz versions of rbldnsd zone files available
by Jeff Chan 10 Jul '06

10 Jul '06

At Raymond's suggestion, we are now making available gzipped versions of the rbldnsd zone files. They are significantly smaller than the original text versions. This is to correspond to the recent addition of gzipped file support to rbldnsd: http://www.corpit.ru/mjt/rbldnsd/NEWS Note that most installations and applications should only need to use the multi.surbl.org list, since multi includes all production lists.

sc2 removed, please update any test and nameserver configs
by Jeff Chan 10 Jul '06

10 Jul '06

sc2.surbl.org, the test list for the revised sc list, has been removed. If you were using it in test configurations, then please remove it. If you were serving the zone for public queries then please remove the zone from your nameserver configs. Thanks for your help in testing and serving it. The sc list has been using the revised data for about a year, so sc2 has been redundant since then. Cheers, Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

Exim script now checks MIME attachments
by Jeff Chan 02 May '06

02 May '06

Erik Mugele reports that he has added MIME support to his Exim script for checking messages against SURBLs: "I have released a new version of my Exim Perl script. In conjunction with the proper Exim configuration, the script will now check for blacklisted domains in URLs in decoded MIME attachments (i.e. base64). Details at: http://www.teuton.org/~ejm/exim_surbl/ " Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

milter-uri.pl is a Perl Sendmail milter
by Jeff Chan 28 Apr '06

28 Apr '06

Steve Freegard of Fort Systems Ltd. reports that milter-uri.pl is a basic Sendmail milter written in Perl using Sendmail::PMilter and SpamAssassin libraries. http://www.fsl.com/support/milter-uri.pl By default it uses "the 20_uri_tests.cf rules file (so it is relatively light) to strip the URI's from a message and then check them against" SURBLs. Other SpamAssassin rules should be configurable. Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

MEFilter and milter-link add SURBL support
by Jeff Chan 28 Apr '06

28 Apr '06

Two applications add SURBL support to Sendmail and MailEnable respectively: Anthony Howe of SnertSoft reports that his milter-link/0.1 for Sendmail "extracts URLs from the message body (text, HTML, and/or MIME encoded)" and checks them against SURBLs, or after domain resolution against RBLs. Written in C, milter-link does on-the-fly MIME decoding without using temporary files. http://www.snertsoft.com/sendmail/milter-link/ Martyn Keen reports that his MEFilter, a bolt-on for the MailEnable mail server, adds beta SURBL support. Test results are very favorable. http://www.mefilter.com/ Cheers, Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

Welcoming new public name server
by Jeff Chan 09 Mar '06

09 Mar '06

We'd like to welcome and thank the addition of a new public SURBL name server b4.surbl.org administered by: Alice's Registry, Inc. Without our public nameservers and the help of their administrators, SURBLs would not be possible. Our thanks to all of them! Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

Exim SURBL Script Updated
by Jeff Chan 21 Feb '06

21 Feb '06

Erik Mugele reports: __ I have finished a new version of the embedded Perl script that can be used by Exim to do SURBL filtering. This release more closely follows the SURBL Implementation Guidelines. In particular it makes use of the ccTLD list provided on the SURBL website. A good portion of the script was rewritten to make it more efficient and to do far fewer lookups against the SURBL nameservers. This also means less processing/waiting on mail servers running the script. Downloads, instructions and details can be found at http://www.teuton.org/~ejm/exim_surbl __ Cheers, Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/
