This article on SendGrid is helpful. You do need to set up a separate MX record on a subdomain (or other domain) for inbound "parse" replies.
NodeBB 1.13.3 - OSSEC issue
I use NodeBB 1.13.3 on Ubuntu 18.04 where OSSEC is also installed on.
While using NodeBB, after some clicks I get the following message from OSSEC:
"High amount of POST requests in a small period of time (likely bot)."
Then my IP address gets blocked
If I stop ossec, then all works fine.
Any idea how to resolve this - much appreciated !
I have resolved this issue by adding the following rule to local_rules.xml.
