I have been reading all the DKIM related posts I can find, both on this list and other places. For a mailing list, would I have to expand my SigningTable in any way? My opendkim SigningTable currently only has an entry for *@list.example.com(which is associated with list._ domainkey.example.com). But /var/log/mail.log shows a lot of entries like this: no signing table match for [some member of the list] > So I think signing doesn't take place for messages passing through the list because of the way I set up my SigningTable. But I didn't find any specific info on setting up a SigningTable for a mailing list. The mail log file also shows entries like this: May 12 21:45:42 localhost opendkim[20976]: 55A4C122C5: DKIM-Signature > header added > Although when I manually inspect emails I receive via the list from other users they are never DKIM signed. (My own messages are signed -- and I certainly match the signing table. But I can't match the log entries up to individual users or to list activity, so far; therefore, a number of things are still unclear.) (Similarly, my trusted hosts table is limited to my own Mailman/Postfix server. But I can't imagine it would be wise to change that.) ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
