Email messages inconsistently signed

[lnicola]

• a Welcome to the "postgis-tickets" mailing list message I got was not DKIM-signed
• a [SCM] PostGIS branch master updated. 3.4.0rc1-749-g42f04a29e message was signed, but with a broken signature:

    dkim=fail (message has been altered, 2048-bit rsa key sha256)
      header.d=osgeo.org header.i=@osgeo.org header.b=HFXPb4eW
      header.a=rsa-sha256 header.s=mail;
    dkim=pass (2048-bit rsa key sha256) header.d=osgeo.org
      header.i=@osgeo.org header.b=B8QP3oc/ header.a=rsa-sha256
      header.s=mail;

• [SAC] [OSGeo] #3013: Submission service to send formal emails (was: Mail Submission Agent service to send formal emails) was not signed at all
• strk says outgoing messages are signed, not sure which ones

• The [SCM] message comes from tracsvn machine via a git hook. This should go via postgis-ticket so not sure why signature is broken, can you tell ?
• The [SAC] message is from sac mailing list, which is currently modifying the message and should stop doing so, see ​https://trac.osgeo.org/osgeo/ticket/3011#comment:23
• The welcome message should be coming from pickup service but I'll be able to tell more if you provide a message-id for it

The opendkim configuration is now in ansible, if you want to take a look, lnicola

Maybe we could use the trac wiki to document the various ways outgoing emails are signed, I've just received one from the new discourse service (discourse.osgeo.org) and it is not signed at all:

dkim=none; dmarc=pass (policy=none) header.from=osgeo.org; spf=pass (spool.mail.gandi.net: domain of                                             
        "SRS0=JIbU=HZ=discourse.osgeo.org=noreply@osgeo.org" designates 140.211.15.3 as permitted sender) smtp.mailfrom="SRS0=JIbU=HZ=discourse.osgeo.org=noreply@osgeo.org"
