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 devs@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 On 11/08/2016 03:40 AM, Pascal BASTIEN wrote: > 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 > > Pascal > ---------------------------------- > Received: from nm43-vm5.bullet.mail.gq1.yahoo.com > (nm43-vm5.bullet.mail.gq1.yahoo.com [67.195.87.220]) > xxx > DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=yahoo.fr; s=s2048; > t=1478593132; bh=g3zLYH4xKxcPrHOD18z9YfpQcnk/GaJedfustWU5uGs=; > h=Date:From:Reply-To:To:Subject:References:From:Subject; > b=N6C8UltuP6jp4mZaWG43Y1ngel4R75RdftqTuXxYHngnseuGe5/2k2/H5pwVcJVe34gjtB33vMZm1j4yZ56M8++zNl4Asb4xV/6wwF+JL+ZGlcXTmfJdGlx5+GdukOzN6bX9Dz9Lvp5GpsYHZnWE8eANw0SeJ9t9wcvzKmNOYW+t9S53N27nfRfjYAwm7iZVmUsgbbZlpnW3NYrPOLoBGZX67aq6gsq877LKUyLLgLP5oszQnx3cUZAsgmjRuSYIIzjF42vfzjVjs7rOoO7royNl5O8BeFlgpevF/BDk2g2K7KXRTkkKtmDMxxxx > > > -------------------------------------------- > En date de : Lun 7.11.16, Sergiu Dumitriu <ser...@xwiki.org> a écrit : > > Objet: Re: [xwiki-users] Lots of disabled Yahoo email addresses on the > xwiki.org lists > À: "XWiki Users" <us...@xwiki.org>, "XWiki Developers" <devs@xwiki.org> > Date: Lundi 7 novembre 2016, 15h40 > > By the way, all of > Pascal's and Julio's emails (and other yahoo > users) > end up in my spam folder because of > the broken DKIM signatures. > > On > 11/07/2016 09:24 AM, Sergiu Dumitriu wrote: > > This is partially XWiki's > infrastructure fault, too. > > > > DMARC doesn't work well with mailing > lists, since they tend to break > > DKIM > signatures.
