I think this is largely an Exim-specific problem. It's unfortunate that the default configuration deliberately breaks mailing lists by asserting that mailing-list related headers do not exist. Most other DKIM deployments do not do this. DKIM itself has been designed to be compatible with mailing lists. For many years, I believed otherwise, but I was wrong. I'm sure the Exim defaults are just a historic accident, but they are exactly what they would look like if someone wanted to use Exim's market share to score a point against DKIM. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
