Note: groups.io will be down for maintenance on Wednesday, October 5th, starting at 9AM Pacific Time (4PM Wednesday October 5, 2022 UTC), for approximately one hour.
Anyone feel like tackling this one?
ANY time I respond to a Groups.io using email, vs. signing in and doing so via the Website, I get a TON of SPF and DKIM failures back for various reasons from all the different servers in between me and wherever the response goes.
MY SPF and DKIM are perfectly configured. I monitor 100% of all messages from ALL email addresses from my MX server.
This is obviously something that the Groups.io system is doing in processing, et al.
I am concerned that these failure reports will hurt my Mail Server's reputation and thus impact deliverability of email from my clients, me, et al...
