First, this has nothing to do with MailScanner.

Second, I can't at all see that exim doesn't try to resend the mail.

cr-mip.fr publishes 3 MX records

10 114-154.206-83.static-ip.oleane.fr.
20 mail3.systonic.fr.
30 mail2.systonic.fr.

exim tried the highest priority MX 114-154.206-83.static-ip.oleane.fr and
got the 450 (greylisting) reply. It then tried the second priority MX
mail3.systonic.fr) which accepted the mail.

The problem, if any is in the mail configuration for the cr-mip.fr
domain which publishes 3 MX records and only applies greylisting on
one of the MXs, and possibly doesn't properly deliver mail sent to the
backup MXs.
