Anyone having this issue with bouncing members?


 

Hi, hope everyone is well and staying safe!
I checked my bouncing members list today and found several there, all with the same message as the response:
": 421 CMGW Connection refused, too many sessions from 66.175.222.12. Please lower the number of concurrent sessions. IB007 <>?"
Their email delivery history shows many responses of
": 550 5.1.0 <66.175.222.12> This IP has sent too many messages this hour. IB504 <>"
going back to January or earlier. But they weren't bouncing then. I check the page once a week at least.
Seems strange that they all have the exact same message and IP address. I googled the?IP and it seems to be from New York. We're located in Canada.
Is this some kind of spam takeover? Are the members' accounts (email and/or ) compromised??
Is anyone else getting this message for bounced members?
Any advice would be helpful.?
Thank you, Sally?
