Hi,
We have a repeated problem with emails from our group members not being delivered due to exceeding the 'rate limit ' of groups.io connections to our server (and apparently the servers of Gmail and Outlook etc)..
It is (was, our host has now increased it) very low 1.2 email per hour. When I queried this, the response was:
"Indeed 1.2 connections per hour is a low value but it's because
their network is considered to be suspicious due to their IPs being
blacklisted. I've increased the limit which should allow the emails to
come through."
And,
"T!he issue started with groups.io IP getting blacklisted, the server
then detected several connections from this IP and flagged it as
suspicious and because of that suspicion the amount of connections
allowed for this IP was ratelimited to prevent spam getting into our
servers."
Has anyone experienced this on their servers . .? And found a solution?? Really frustrating. Do groups.io know their IP's are blacklisted?
Thanks,
Lynda
