questionable email filtering policies?

assume i have already done this, and received a completely and utterly useless response from yahoo indicating they have absolutely not the slightest clue. -Dan On Thu, 23 Jul 2009, Ben Carleton wrote:

I'm not sure which is worse: 1) That they filter their abuse mailbox. 2) That they outsource their abuse mailbox (and potentially others) to Yahoo. 3) That they're doing (2) and they're apparently a few orders of magnitude bigger than "Joe's Bait, Tackle, and Internet Emporium". "And they wonder why we block their e-mail.." -- the NANOG lurker in the next cubicle, standard response when a site's demonstrated configuration clue level is so low to render constructive dialog improbable.

BT outsources all of their mail to Yahoo. It actually works pretty well, either POP or web mail. R's, John

How about writing to Bruce Schneier and explaining the problem? He's Chief Security Technology Officer at BT. http://www.schneier.com/ Steinar Haug, Nethelp consulting, sthaug@nethelp.no

On the topic of mail rejection I have come across a few sites that reject mail, even to postmaster@, from domains that have one or more ipv6-only MX records listed (i.e. a domain name with AAAA but no A record(s)). The common factor seems to be mimedefang.

Plain sendmail has got a similar issue, especially if the best MX is IPv6-only. I learnt that the hard way---and it speaks for the quality of IPv6 testing that the "IPv6 considerations for SMTP" RFC (forgot its number) doesn't even come close to mentioning this issue, preferring to talk about bizarre reachability concerns. 8-P -- Florian Weimer <fweimer@bfk.de> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99

Is it an antispam test that fails in sendmail, or does delivery fail after the first MX lookup is 'unexpected' (yikes)? As a small ISP that runs our own mail for the most part, I'm curious if there are any lists out there of antispam tools that have been tested in a functional ipv6 environment. By antispam tools, I mean things like mimedefang, snertsoft's milters, mailscanner, spamassassin (and dns perl modules), and other 3rd party milters or filters that might be less well known, but that do dns tests, or sanity tests of some kind (milter-dnsrbl, milter-regex, etc).
