This parameter is one built-in to Postfix, and "postconf" does not report
user-created parameters.
Also, setting this parameter won't "slow" down mail to Yahoo, it will
in fact increase the number of messages sent, while lowering the number
of recipients per-messages (assuming some messages have more than 2
Yahoo recipients, otherwise it has no effect at all).
If your prorblem is output-rate or destination concurrency, you are using
the wrong tool. If you must reduce the recipient count per transaction,
IIRC Yahoo seems to prefer 10 recipients per-message rather than the
RFC required 100.
