[arch-general] DKIM signed messages to mailing list - issue
Each time I send to the arch list I get a postmaster complaint about DKIM from postmaster@bctpe4hbiu.org My domain DKIM signs all mail - however my DKIM signature is passed through by the mail list package and of course now the message will fail DKIM check as the header has been modified and is no longer coming from my domain. I guess the list should remove incoming DKIM headers? gene

So go complain there. It is a problem of a list member’s server, and not Arch Linux Mailman’s. -- Kwpolska <http://kwpolska.tk> | GPG KEY: 5EAAEA16 stop html mail | always bottom-post http://asciiribbon.org | http://caliburn.nl/topposting.html

I don't fully agree - strictly speaking passing through inbound DKIM headers as the arch mail list server is doing is not following the guidelines of RFC 6377 [0] which (among much long discussion) suggests: The best general recommendation for dealing with MLMs [1] is that the MLM or an MTA in the MLM's domain apply its own DKIM signature to each message it forwards and that assessors on the receiving end consider the MLM's domain signature in making their assessments. (See Section 5, especially Section 5.2.) This is not required by the RFC just recommended. That said it is indeed a tricky issue ... I'm just saying the mail list server is not guilt free here. That said I am not sure what mailling list server options there are regardning DKIM. The receiving server probably should not be emailing the DKIM author's postmaster either - so that is a no-no as well - it should just reject or accept message and not creating more spam. gene [0] http://tools.ietf.org/html/rfc6377 [1] MLM = mailing list manager.
