Right. This is why ISC is working on a real solution to the
overall problem. According to the article by Declan McCullagh at
<http://news.com.com/2100-1032_3-5077530.html>, there should be a fix
for this published by tomorrow.
the expectations for .com and .net to not
have wildcards were all set many years ago, and it's the violation of
those
expectations that's got people angry enough to publish patchware about
it.
New versions of BIND 9.{1,2,3} have just been released:
The "Snubby" mail rejector daemon has been now upgraded to version 1.5!
It accepts EHLO and most SMTP commands, and looks RFC compliant. Once
again for the BCP area we must account for this behavior and similar
theoretical DNS issues in BCPs for spam tools and MUA/MTA authors.
Additionally, as per below log, it accepts mail addressed to
<postmaster> as per section 4.5.1 of RFC 2821. It does not accept mail
addressed to <postmaster(_at_)some-non-existing-domain(_dot_)com>, so misaddressed
mail bounces UNLESS the sender's MTA/MUA uses the <postmaster> format.
The mail log appears below:
