Greetings,
I'm about to setup a new mailing list server. It will use Mailman 3,
which is
able to add ARC signatures to incoming messages. The lists will also
rewrite
the From:-header and to match the lists name and domain. I'm unsure if
outbound messages should also be DKIM signed or does it suffice to add
ARC
signatures?
why not add ARC to amavisd new first ?
like DKIM already is, i ask since this can help not rejecting maillists,
where the maillists breaks dkim before ARC sign :/
mailman should only ARC-seal and ARC-sign before breaking DKIM, but
avoid breakin DKIM please
workaround for breaking DKIM is simply silly
note i talk about spamassassin now ? :)
outbound should not be dkim signed in mailman, dont do this
