Pierre, all you need for the secondary MX server is the hostname entry in 'locals' (which must match the hostname listed in the MX record exactly, of course).
When courier accepts the email and then recognises that this email address is not held locally it will consult the dns itself, see that there is another preferred MX record, and try to relay the email to that hostname. Presumably that host is temporarily unavailable, so the email will just sit in the mailq as usual until the primary MX is available again.
