Interesting ... what do they hope to accomplish? Are they implying they have some kind of blessing hidden (or not) within the SA default settings (perhaps the ham indices like DNSWL)? Perhaps instead they are proposing third-party SA whitelisting rules ... but then those would be openly available (and they're not, or they're poorly linked). I can only conclude that their service is just a collection of suggestions for bypassing filters, which certainly seems to be the aspiration of their blog at http://blog.streamsend.com/ >> Not my email though. >> header J_STREAMSEND X-Mailer=~/StreamSend/i >> score J_STREAMSEND 10 This seems to be the most common kind of StreamSend-related material online (discounting uninformative reviews of the service and their own marketing material, which is quite broad-reaching). They're firmly lodged in URIBL_GREY (I found hits in June 2008 and April 2009 at least), they were in JM_SOUGHT this past January as __SEEK_YRSN7R (svn r730688), and there are plenty of how-tos for blocking them in various software like postfix and SA. Looking at the third-party reviews, StreamSend doesn't look like anything special; no reputation be it good or bad ... though many of these reviews say they lack a spam filter tester, which has become a core business model, so the reviews are quite aged. The SpamAssassin project would only be interested in blocking them if they exhibit some gross negligence when it comes to opting out or some over-aggressive practices. Other than that, it's up to the indices like URIBL and SOUGHT to nail them on more specific (and thus more time-sensitive) abuses.

Right, I see that at http://www.streamsend.com/returnpath_toolset.htm ... Interesting, but not surprising. That just means they use Return Path's system to clean (and relay?) content they send for their customers. This should do a good job of avoiding DNSBLs. As with DNSWL and SPF/DKIM, anything that might be conceived as a way to bypass spam detection is a useful tool to a mass-mailer. There's a reason SA lacks strong negatively scored rules. Habeus was abused and removed for this reason (StreamSend participated in that!). Does StreamSend monitor this list? With their purported spam-fighting-curtailing, I'd figure almost certainly... Do they have comments, or do they prefer to stay in the dark? Speaking of anti-anti-spam, this is pointless as it can't be trusted: > _________________________________________________________________________ > This email has been scanned and certified safe by SpammerTrap(r).
