if the bounce has to go back to the MAIL FROM: address (as I think it
does) then yes, you can only have one recipient. [Multiple senders
are allowed, AFAIK, in the From: headers].
You could do something like:
deny message = Sorry, only one recipient per bounce message
condition = ${if eq {$sender_address_local_part}{}{yes}{no}}
condition = ${if >= {${eval:$rcpt_count}}{1}{yes}{no}}

this will reject any RCPT TO: other than the first for null senders
(I'm not sure about if $rcpt_count is updated before the recipient is
accepted, if it is you must have a strict > instead of a >=
condition).
I just hope the callout does not ever batch.
Untested.
