SMTP module(domain reports: 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
