We're not seeing any activity from that IP address on any of our
mail servers, and that CIDR is not in any of our block-and-forget
lists.
It is showing up in three DNSBLs though:
https://multirbl.valli.org/lookup/104.171.22.220.html
The SpamGrouper DNSBL is unlikely to result in active blocking, but
eMail from that netblock could land in spam folders. However, the
other two DNSBL entries are from SpamRATS, which I happen to know is
being used for SMTP-session blocking by some postmasters.
