66.175.222.12 is the IP address of Groups.io's outbound mail server.

Some Mail Service Providers suddenly take it upon themselves to bounce Groups.io mail for reasons nobody really knows; getting an MSP to admit to this is likely to be tricky. One blind spot is that any group owner can only see bounces for their own group; there is no means of knowing (without asking the individuals concerned) how many groups they subscribe to and how many emails they receive as a result. "Too many messages" is a somewhat unclear description of the problem; how many is too many!

Check your members' mail providers (the Bouncing list is a good place to start) to see if there is anything that might be statistically significant.
