Subject: [mailop] Hotmail and 4.5.1 4.7.500 Server Busy with some ASxxx attached
Hello,
did anybody get any sensible answer from Hotmail Sender Support about the
451 4.7.500 Server busy. Please try again later from []. (AS843)
[.prod.protection.outlook.com]
deferring a large percentage of traffic forever (even a 48 hours limit to
retries won't help), obviously from DKIM-authenticated transactional messages
emitted by top-reputation, SNDS-green, no-problem-whatsoever until the suspect
recent infrastructure switch on their side IPs,
and is willing to share the love you got from them?
Sometimes the AS843 is AS844 instead.
Have a nice day!
Davide
