FWIW, RFC 2821 says: "Rejection of messages (for excessive recipients)
with fewer than 100 RCPT commands is a violation of this specification."

I think this is a bit outdated and valid smtp clients should be able to
handle lower limits. OTOH, the designated error code is 552, which clients
could interpret as a permanent error and therefore will not try to send to
this recipients again.
