Package: dkim-filter
Version: 2.6.0.dfsg-1
Severity: important

I tag this bug as important because some people are prevented from using
DKIM due to the configuration of some list servers that are important to
them (such as lists.debian.org).

The DKIM milter should support the use of the length field based on the
recipient address.  Any mail sent to an address matching @lists\. should
have the length field used by default.  The list server will either strip
the DKIM field (as the version of Mailman in Lenny does) in which case it
doesn't matter what you do, or it will send the mail through with no
changes (as the lists.debian.org server does) in which case any
subscriber who performs DKIM checks will regard the mail as invalid if
it does not use the length feature.

The length field can be used for all mail to avoid this problem, but
then you get the same issue if the mail server prepends [listname] to
the Subject line.  To resolve this the DKIM milter needs to support a
list of recipient addresses for which no DKIM headers will be used.

Ideally the list server would fix this.  I've filed the above two bug
reports against lists.debian.org and I expect that if nothing else a
routine upgrade after Lenny will resolve it.  But we should expect that
there will be significant numbers of mail servers out there that won't
be upgraded for years.
