Hi,

Several folks have let me know that my messages sent via lists.xen.org
are marked as spam / spoofed, especially when using Gmail to receive
Xen mail. I believe this is because outbound Amazon email contains a
DKIM signature. When Mailman modifies my message and re-sends it, the
DKIM signature is invalidated [1].

To work around this, Mailman 2.1.10 and later contain a configuration
variable called "REMOVE_DKIM_HEADERS" [2]. Perhaps if this were turned
on we'd work around the problem.

Matt
