Re: [swinog] Has Bluewin a DNS Problem

Salut, Kurt, On Wed, 26 Mar 2008 15:03:40 +0100, Kurt A.

It is most likely that either the software blows up or that it only ever considers the entry it receives first. (Most likely the software blowing up will not even be remarked but instead the mail will be rejected silently.) 2. Since a lot of people use personalized domains now in their mail addresses (me(a)first.lastname.ch, bla(a)pascual.garnier.name, whatever), the people who use such a setup will be strongly discouraged very quickly and be forced to drop it, since they want to still be able to send mail, most likely. We should not make such stupid moves just to encourage them to adopt such a setup. > Under the line, it is likely not a DNS issue, but the inability by > some mail or AS systems resolving lists.

It is also a DNS issue, depending on the number of results returned; the size of a DNS/UDP response is limited to 1 UDP packet, which again is limited in size. Not everyone uses DNS over TCP, and it is unlikely to be adapted just because of such a stupid and useless SPAM filtering measure. Tonnerre

Trying to work around them with a dodgy DNS setup is not the right course of action, IMHO. > If this approach works out, it could be considered. It is not illegal. Correct - it's just silly and it doesn't work as expected. 1) a properly working resolver library will return multiple records rotated once for every lookup, so you're never guaranteed to get the same answer to a reverse lookup. 2) most applications, e.g. mail-servers, that do reverse lookups do not expect more than one reply, and will always only process the first one. > It's just against what we are used to over the last 20+ years. Plus it doesn't work. /Per Jessen, Herrliberg -- http://www.spamchek.com/ - your spam is our business.
