The reason that my emails from the CentOS list are marked as spam by Google is that our domain employs DKIM and SPF for outgoing SMTP traffic. The CentOS mailing list manager is the stock Mailman package provided with CentOS. That version mangles the originator's mail headers and body, thus invalidating the DKIM signature. It then sends the message out as originating under the original sender's domain but from an unauthorised SMTP server address, thus triggering the SPF failure.
If I understand the problem correctly your emails sent out by the Centos mailing list (using Mailman) are considered by Google et al to be spam. The fundamental reason you believe is be your site's usage of DKIM.
Why can't your site get a cheap VPS anywhere in the world and route outgoing emails, without DKIM, through the VPS ? Cost in EU is less than GBP 80 per annum (circa EUR 96 p.a.) It is easy to achieve using Exim.
But logically that will defeat the whole reason of using DKIM, won't it?
But .... is not his problem that when he sends an email to this mailing list, Google - when it gets its metaphorical hands on the output from this mailing list, whilst delivering it to some recipients - declares his email as spam ?
Everyone knows that when dealing with large organisations (especially North American ones and their global imitators), one can waste enormous amounts to time pleading with them to do simple and reasonable things properly.
He needs a solution. I proposed what I thought was a relatively quick and cheap solution.
Another solution is for the mailing list to delete all previous headers on receipt of incoming emails - perhaps that might work ?
