Fair enough, except that list servers are supposed to be configured in such a way so as to get around this. A list server *should* send a separate email to each user in a list, NOT one email to ALL the users in the list. The latter will definitely get "DMARC'd" as spam, especially if the addresses are not in the BCC field. Also, the list server *should* send the emails in a throttled way, so as not to raise any flags.
It may be that gmail has tightened their DMARC rules, and so an adjustment needs to be made in the list server to accomodate them. If this cannot be done, it might be advisable to use a different domain. Mail issues like this are definitely a nuisance, but in the modern age where email accounts are getting compromised, providers are understandably a bit skittish. Bob S > On Jan 3, 2017, at 09:08 , J.
