FYI: I don't see any issues with 45.32.136.82. It's included in the
"spamgrouper" DNSBL, but I'd be surprised if anyone was using that
for blocking since that will cause a lot of collateral rejections and
easily become a technical support nightmare almost immediately:
https://multirbl.valli.org/lookup/45.32.136.82.html
I have noticed that HotMail.com accounts are bouncing sporadically
over the past few years, and some users have found that re-sending
seems to resolve the problem ... sometimes.
I'm not suggesting that you consider re-sending to be a reliable
option given the permanent error code response you received, but
perhaps there's a different contact that you can send to instead?
