Diagnostic-Code: smtp;450 4.7.1 Client host rejected: cannot find your
reverse hostname, [157.55.1.150]

(Verified this using various public DNS servers, to exclude potential
local
issues)

Anyone here who has proper contacts to give them the clue-bat?

noc () microsoft com will probably understand or at least point you in the
right direction.
