ANNOUNCE: SpamAssassin 3.0.0 released, includes SURBL support
by Jeff Chan 22 Sep '04

22 Sep '04

Released today, SpamAssassin 3.0.0 has support for SURBLs built-in and enabled by default. It checks multi.surbl.org using the command urirhssub in the URIDNSBL plugin. http://spamassassin.apache.org/full/3.0.x/dist/doc/Mail_SpamAssassin_Plugin… If you administer a high volume mail server processing 100k messages per day or more, please set up a local DNS mirror for your own use of the SURBL zone files using rsync and rbldnsd as described in some of the links on our rsync signup form: http://www.surbl.org/rsync-signup.html If you are able to host public DNS for the SURBL zones, please let us know. Pre-release traffic was about 70-80k bits per second, and we expect that to go up at least 5-fold, but that's just an estimate. Cheers, Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

ANNOUNCE: SURBL TTLs optimized at 15 minutes
by Jeff Chan 17 Sep '04

17 Sep '04

After trying DNS TTLs at 1 hour, 25, 20, 15 and 10 minutes, it appears that 15 minute TTLs optimizes both name server traffic and the quickness of records being added or deleted from the lists. Therefore, we are standardizing on 15 minute TTLs for all SURBLs. Note that this result applies to SURBL data and uses of it. It may or may not apply to other types of RBLs.

ANOUNCE: Welcoming new public name server, misc name server news
by Jeff Chan 17 Sep '04

17 Sep '04

We'd like to welcome and thank the addition of a new public SURBL name server administered by: Chris Stone of AxisInternet, Inc. Without all of our public nameservers and the help of their administrators, SURBLs would not be possible. Our thanks to all of them! Some additional name server news: all of the name servers which we had temporarily commented out while they were being repaired have been fully returned to service. A name server status page can be found at: http://www.surbl.org/nameservers-output.html Also in case we haven't already mentioned it, the name servers are now organized into letter names like a.surbl.org, b.surbl.org, ... through n.surbl.org, and each name round robins into two or three servers. As more are added, we will try to balance them all at three servers per name, so that traffic is balanced overall. Having more than one server per name lets us comment one out without needing to change NS records in the subdomain zone files and delegations, when maintenance on a particular name server needs to be done, etc. It also keeps the SURBL DNS packets smaller to have fewer name servers listed in the NS records.

ANNOUNCE: Top SURBL DNS blocklist hits joins top whitelist hists
by Jeff Chan 17 Sep '04

17 Sep '04

To follow up on an earlier announcement, in addition to a list of the top SURBL DNS queries that hit whitelists: http://www.surbl.org/dns-queries.whitelist.counts.txt we've added a list of the top blocklist hits: http://www.surbl.org/dns-queries.blocklist.counts.txt Though the sample size is somewhat small at 32k queries over the trailing 48 hours, the data may perhaps be useful for expiring records from blocklists or checking whitelists. We can increase the sample size if anyone thinks it worthwhile. Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

ANNOUNCE: Top SURBL DNS queries and whitelist hits
by Jeff Chan 07 Sep '04

07 Sep '04

We've made a list of the top SURBL DNS queries into my name server: http://www.surbl.org/dns-queries.counts.txt and a version with only whitelist hits: http://www.surbl.org/dns-queries.whitelist.counts.txt The sample size is somewhat small at 32k queries over the last 48 trailing hours, but it's still somewhat interesting. Specifically 2000 queries are sampled every 3 hours. (Please ignore some of the junk at the end of the unwhitelisted counts. That's stuff left over from DNS packets which I haven't cleaned out yet.) I'm slightly surprised how high in the total rankings some spam domains are. That represents a huge amount of spam sent and blocked. :-) Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/
