These options say how Postfix will DELIVER mail. They DO NOT say
what mail Postfix will RECEIVE from a sender.

That depends on how Postfix RECEIVES mail from the sender. With
SMTP, there is smtpd_recipient_limit which must be 100 or more if
you don't want to lose mail from legitimate senders. There is no
explicit limit for the number of Postfix sendmail recipients
(that depends on the queue file size limit and available space
in the file system).
