The host commands give the same results for me too but sa-update 
fails.

It seems to be happening in this section of code (lines 539 to 547):

    if (!defined $newV) {
      my @mirs = do_dns_query("mirrors.$channel");
      if (defined shift @mirs) {
        dbg("channel: no updates available, skipping channel");
      } else {
        channel_failed("channel: no 'mirrors.$channel' record found");
      }
      next;
    }

At this point $newV is defined but is an empty string so do_dns_query 
is invoked to lookup the TXT record for 
mirrors.updates.spamassassin.org which returns an empty arrayand 
results in channel_failed("channel: no 'mirrors.$channel' record 
found").
