MailChannels’ Traffic Control now free-as-in-beer

I’m on the technical advisory board for MailChannels, a company who make a commercial traffic-shaping antispam product, Traffic Control. Basically, you put it in front of your real MTA, and it applies “the easy stuff” — greet-pause, early-talker disconnection, lookup against front-line DNSBLs, etc. — in a massively scalable, event-driven fashion, handling thousands of SMTP connections in a single process. By taking care of 80% of the bad stuff upfront, it takes a massive load off of your backend — and, key point, off your SpamAssassin setup. ;)

Until recently, the product was for-pay and (relatively) hard to get your hands on, but as of today, they’re making it available as a download at Apparently: “it’s free for low-volume use, but high volume users will need a license key.”

Anyway, take a look, if you’re interested. I think it’s pretty cool. (And I’m not just saying that because I’m on their tech advisory board. ;)

    Nice to see that they’ve opened some of this up. :)

    Have to say, though, that I really enjoyed the irony of being spammed by MailChannels last year. Somehow I doubt I was the only one; they harvested the e-mail addresses out of a competitors mailing list (and acknowledged doing so after I’d complained). I’d e-mailed them regarding the issue (and irony of being spammed by an anti-spam company) and got the most wonderous response from Desmond Liao, “As a result of your [my] complaint, we intend to review our list acquisition policy with the goal of shifting towards permission-based marketing.”

    Although they may have a technically sound product, spamming potential customers makes them no better (IMO) then the other guys they’re trying to keep out of my Inbox.

    Wow I was blogging about this last night but got distracted.

    I looked at it yesterday and decided that 10k/day is not enough for my personal mailhost.
