I'm watching my exim logs right now and can confirm that the gentoo mailing list server does cope well with greylisting, i.e. it attempts delivery again after a few minutes. Also, messages from me to others pass DKIM checks, unless they are modified by what you suggested: > DKIM fails on many mailing lists.

I'm pretty sure that I'm not the first one to ask, but given that DMARC and DKIM seem to have become a thing, would it not be "better" for delivery if the mailing list software removed the DKIM signature if it modified a header that was signed? s.
