They finally did, and the new version (1.5) of the "Snubby Mail Rejector" does work better. It handles multiple "RCPT TO:" commands better - the previous version 1.3 would always reply 550 to the first, but 250 to the next. And the new version even does ESMTP with the PIPELINING extension - this will save quite a few packets globally. <simon@dafladshflhfldkshflaasdf.com>,<leinen@dafladshflhfldkshflaasdf.com>...
