In your bofh file, consider (quoted from the courier.html file):
maxrcpts N [hard]
Accept the first N recipient addresses per message, maximum. The
remaining recipients are rejected. An optional verbatim token "hard"
specifies that the remaining recipients will immediately be returned as
undeliverable (otherwise the remaining recipients are rejected as
"temporary unavailable", and may be accepted on a later delivery
attempt). If not specified, the first 100 recipients are accepted.
I would also take a look at your queuehi, queuelo, and queuefill
parameters. Also consider telling us what they are, and the current
situation in all forthcoming emails (details like load,
deliveries/minute, MAXDELS, queue{hi,lo,fill}, etc... On debian the
'courier-mtaconfig' program displays the queue* values.
