I keep getting these errors/warnings: "no IP address found for host
relay_from_hosts" in the logs like this...
2021-02-09 11:46:45 SMTP connection from [10.100.7.3]:46172
I=[10.100.1.3]:25 (TCP/IP connection count = 3)
2021-02-09 11:46:45 no IP address found for host relay_from_hosts
(during SMTP connection from (scc) [10.100.7.3]:46172 I=[10.100.1.3]:25)

What does this mean? I don't have any reverse DNS verification enabled,
but is relay_from_hosts a special variable with some hidden meaning in exim?
What I think is the relevant parts of the configuration (and the only
places that relay_from_hosts is used)..
