The message with `Message-ID: <e4c333ab-
19b0-e733-91a6-56b29c941dbe@ec.gc.ca>` sent to SolKatzAward mailing list
on May 9 2023 ended up in my spam folder because of:

{{{
Authentication-Results: spool.mail.gandi.net; dkim=fail ("body hash did
not verify") header.d=ec.gc.ca header.s=selector1 header.b=HdthrUcz;
arc=reject ("signature check failed: fail, {[1] =
         sig:microsoft.com:reject}"); dmarc=fail reason="SPF not aligned
(relaxed)" header.from=ec.gc.ca (policy=none); spf=pass
(spool.mail.gandi.net: domain of
         "SRS0=ZnJu=A6=lists.osgeo.org=solkatzaward-bounces@osgeo.org"
designates 140.211.15.3 as permitted sender)
smtp.mailfrom="SRS0=ZnJu=A6=lists.osgeo.org=solkatzaward-
bounces@osgeo.org"
}}}

Needs be configured to deal with DMARC alleviation.

Comment (by strk):

The signed headers were:
{{{
h=From:Date:Subject:Message-ID:Content-Type:MIME-Version:X-MS-Exchange-
SenderADCheck;
}}}

The Subject was invalidated by adding the `[SolKatzAward]` prefix

Removing the subject prefix might result in passing validation but I'm not
100% sure about it.

Comment (by Jeff McKenna):

Hi I am the admin of that list (and many others), let me know if anything
needs changing. (I have already changed DMARC settings for many of the
lists, per my original steps posted at
https://trac.osgeo.org/osgeo/ticket/2475#comment:36 but I may have missed
a few)

Thanks.
