  • sbl.spamhous.org has new non-spam results

    From Deucе@VERT to GitLab issue in main/sbbs on Saturday, December 06, 2025 18:28:03
    open https://gitlab.synchro.net/main/sbbs/-/issues/1028

    sbl.spamhous.org will return 127.255.255.254 to indicate an invalid query, which Synchronet interprets as a spam indication:

    Also, something seems to be awry with IPv6 lookups since I get this:
    `X-DNSBL: 2610:1c1:1:606c::19:2 is listed on sbl.spamhaus.org (see http://www.spamhaus.org/) as 50.16.218.27`, but a manualy lookup shows NXDOMAIN:

    ```

    Host 2.0.0.0.9.1.0.0.0.0.0.0.0.0.0.0.c.6.0.6.1.0.0.0.1.c.1.0.0.1.6.2.sbl.spamhaus.org not found: 3(NXDOMAIN)
    ```
