postfix how to send to multiple recipients default limit of 1000

The size of the message you are trying to send exceeds a temporary size limit of the server. The message was not sent; try to reduce the message size or wait some time and try again. The server responded:  4.5.3 Error: too many recipients.

We set this in main.cf:
smtpd_client_recipient_rate_limit=0


We didn't specify it before and the default is said to be 0/unlimited and it still didn't change anything.

The real solution is actually in the smtpd_recipient_limit  (set it to however many people you were e-mailing at once, this could be important for large organizations or companies as some still do BCC thousands of people even though mailing lists/aliases/groups are preferable):
smtpd_recipient_limit=5000

Just reload postfix to make it take effect (service postfix reload) you don't need to restart the entire server.
