I'll be eager to see the papers substantiating this. Until then I remain completely skeptical. It's an experimental RFC for a reason. Let's see the data.
ARC is not mentioned here: https://support.google.com/mail/answer/81126?hl=en But nor are mailing lists/listservs. Most of the guidance on "lists" seems to be related to marketing lists (which I hate way more, but gmail seems to be quite forgiving of), vs discussion lists. Also, the error message we're getting speaks to the reputation of "our domain", not our IP block. Otherwise, I would think v4 mail would bounce as well. Now, if that's caused by our staff posting to *other* mailing lists that do not do ARC, we have zero control over that. If it's being implied that gmail is ranking us (i.e. dkim-signed and spf-compliant mail from Mark Andrews to *this list*) with a "very low" reputation because *our* mailman lists don't presently do arc-sealing, then could someone from google please tell me that canonically? -Dan -- --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC FB: fb.com/DanielMahoneyIV LI: linkedin.com/in/gushi Site: http://www.gushi.org ---------------------------
