Thanks for the summary of the issues - I have wanted to investigate<br>
this for some time to see if there's a solution but never had the<br>
chance.<br>
<br>
I have run into so many problems with DKIM and mailing list software<br>
though that I have basically given up using DKIM to reject e-mail. Half<br>
the spam I get is correctly DKIM signed anyway so it doesn't really do a<br>
lot for me.<br>
<br>
I've worked around the problem by whitelisting certain mailing lists I<br>
am interested in. In my case I let SpamAssassin do the DKIM checks so<br>
I can add a rule to drop the spam score down quite a bit if the message<br>
comes through a known mailing list, which still allows it to be flagged<br>
as spam if there are other rules that match besides the DKIM ones.<br>
<br>
Cheers,<br>
Adam.<br>
