Several times, I had bounce problems on the list. Is it related to the problem?

It's not your fault, it's XWiki's Mailman's fault.

The signature verifies that your original email is valid.

But Mailman appends the following to the bottom of the mails:

devs mailing list
d...@xwiki.org
http://lists.xwiki.org/mailman/listinfo/devs

By adding this, the signature now fails. Since yahoo now says that mails
without a valid signature aren't trusted, your email becomes untrusted.

I see now that your mail doesn't have this signature anymore (hurray
XWiki infra!), and is now considered valid:

Authentication-Results: mx.google.com;
      dkim=pass header.i=@yahoo.fr;
      dmarc=pass (p=REJECT dis=NONE) header.from=yahoo.fr

Or actually it's because you sent the mail directly to me, and I see a
copy that hasn't been through mailman. Everybody else got it in the Spam
folder, with the broken signature.

Hello,
It is strange because my emails have a DKIM signature like here (piece of 
header from a mail I sent from my xwiki email to myself at another adress).
Is it sympa who's altering this signature?
Can I fix it (if it is "my fault")?
Thxs

 end up in my spam folder because of

Re: [xwiki-users] Lots of disabled Yahoo email addresses on the xwiki.org lists

[Sergiu Dumitriu]

Forgot to mention the second component of DMARC, SPF, which is also
partially broken by XWiki's infrastructure. The problem with SPF is that
mails for @xwiki.org are forwarded by xwiki.org to xwiki.com
(gmail.com in reality), and this forwarding isn't allowed by a strictly
configured SPF domain. There's no easy fix for this, the only solution
would be to replace self-hosted mailing lists with Google Groups, so
that xwiki.org also becomes an alias for gmail.com

Re: [xwiki-users] Lots of disabled Yahoo email addresses on the xwiki.org lists

This is partially XWiki's infrastructure fault, too.

DMARC doesn't work well with mailing lists, since they tend to break
DKIM signatures. The only way to fix the problem (at least for the
majority of emails) is to remove the footer from the configuration.

So, options:

- remove the footer, which means that "incompetent" users will have a
hard time finding information about unsubscribing, but allows users from
modern email providers to subscribe
- keep the footer, which makes it harder for legitimate users to stay
subscribed
