It was not detrimental for the particular mail message,
which presumably stayed in the queue for a later retry.

It probably is serious in that this is not supposed to be happening,
and deserves to be investigated. Check the log of the MTA
(or the log of the next content filter in a chain), and see
why it failed the reception of mail from amavisd.
