The view from here is that the sending address is no longer listed in
SORBS.  I can tell 'cuz my personal delivery script tags the header with
a list of various interesting DNSBLs, e.g.:

    X-DNSBLs: spamcop, sorbs

which tends to jump out at me.  Also:

    41% dnsblc 80.64.10.60
    42%

Anybody using SORBS to block at SMTP-time (esp. without whitelisting or
taking other factors into account) deserves what they get, IMHO.  It's
not your responsibility to pander to them.  I'm not saying it's not a
valuable metric.. just, well, a race between a receiver making bad
blocking decisions and a sender trying to get around those decisions
helps prop up those bad decisions, and dumbs everything down.

mm  (who probably makes bad blocking decisions too, but would rather
     fix them than having them accomodated)
