Subject: Temporary recipient validation error.

X-Mailer: Apple Mail (2.1084)



SMTP module(domain iwc.com) reports:
midgard.ch.richemont.com:451 Temporary recipient validation error.



I couldn't find a reasonable explanation when googling this sentence


I get the meaning itself of the message, but what happens really behind the scenes?


- what is (not) being validated ?

- What makes the missed validation only temporary, why not fatal ?


Answer would help to understand, how high  the probability is that the "WARNING. Mail Delayed" message does turn into a non deliverable, or not.


Thanks for advise
