Hackers Blamed For MessageLabs Spam Blunder

Posted by timothy on from the won't-happen-again dept.

littlekorea writes "MessageLabs claims to have discovered that the systems of one of its customers were hacked by spammers after an entire block of MessageLabs IP addresses was blocked by antispam service SORBS. Customers of the managed email service had problems with outbound mail last week after MessageLabs' IP addresses were included in SORBS' block list. The Symantec-owned service provider has assured customers it has systems in place to prevent such incidents from happening again."

  1. Please don't use SORBS blocklist by Anonymous Coward · · Score: 5, Interesting

    Sorbs is a really poor block list which I don't think anyone should use.

    I found that my mail server is listed in their list, because 3 years ago the same IP range was allocated to a dynamic IP range.

    Even though it is now a static server address and the whois IP allocation records were long ago updated, and even has the reverse dns saying "static" in the format that sorbs demand, because the ENTIRE /24 network where my server lives doesn't confirm to their demanded reverse DNS standard, they refuse to delist it.

    Their web service is a total nightmare and even their auto responder takes two weeks. As someone who has been working with mail servers on the internet since 1992, I would say please for the love of god, do not use sorbs as an email blocking list.

    Check out Wikipedia for more info on them, they also solicit payments for some delisting which seems completely unethical.
