Dear Incubator-owner,

Last week I send my first email to the incubator@lists.osgeo.org. Even
though the email arrived in the archive, it was not received by all
subscribers.

- It was not received by Jody Garnett
- I did receive it myself, but with a warning that:" This sender failed
our fraud detection checks and may not be who they appear to be."

I looked into the header of the email that I received and it contains the
following:

  Authentication-Results: spf=pass (sender IP is 140.211.15.3)
  smtp.mailfrom=lists.osgeo.org; surrey.ac.uk; dkim=fail (signature did not
  verify) header.d=surrey.ac.uk;surrey.ac.uk; dmarc=fail action=none
  header.from=surrey.ac.uk;

On the Mailman developer Wiki I found a discussion about DKIM trouble:
https://wiki.list.org/DEV/DKIM

So my best guess is that Mailman breaks the DKIM signature that is created
by surrey.ac.uk, and leaves the broken signature in place. Therefore the
message fails authentication tests and is not delivered to all users.

I suppose this is not an issue specific to the OSGeo incubator list.
Nevertheless it seems to be a problem that requires a solution. Please let
me know if you need any further information from me. If you are aware of a
workaround that I can follow that would also be great.

With kind regards,

Alex

Comment (by alexhagenzanker):

I originally reported this bug by email.

I would just like to add that this problem does not seem to occur with the
osgeo-discuss list, where I also posted last week. Perhaps it is possible
to compare the configuration of the osgeo-discuss and the incubator lists,
and copy over the osgeo-discuss settings related to DKIM.

Reassigning to SAC, I'm afraid I'm helpless in this kind of mailman
issues, sorry.

Comment (by jef):

Added `REMOVE_DKIM_HEADERS = Yes` to `/etc/mailman/mm_cfg.py`. Please
verify that it does the trick.

Comment (by alexhagenzanker):

I just tried it with the following message:

https://lists.osgeo.org/pipermail/incubator/2018-February/003556.html

The problem does not seem to be resolved. I receive the same warning that
"This sender failed our fraud detection checks and may not be who they
appear to be."

The email header contains the same snippet that I quoted before. Please
let me know if you need the full email header to help diagnose the
problem.
