I’m running into this with clients for whom we do web site work. Mail not being delivered to Gmail accounts. No bounceback, not being delayed, not marked as spam, just black-holed for no discernible reason. Like, clients losing money because sales leads never make it to them.
Over on mailop a Google employee said that gmail never silently discards email, that mail will always be delivered somewhere or else rejected at SMTP time, and that the only exception is that GAFYD customers (and similar) can set up rules themselves to delete email under some circumstances. I too occasionally experience customers saying their invoices and payment reminders were silently discarded by gmail, so I don't know who to believe. As regards the topic at hand, gmail does seem to go through phases of not accepting our email. While they certainly are tighter on IPv6 and absolutely require SPF, DKIM, DMARC there, other than that I haven't seen v6 be any different to v4 and just swallow it. I know others prefer to only deliver to them over v4. Thanks, Andy
