where can I find the e-mail limits?

I was trying to set the various e-mail related limits by defining an e-mail policy as suggested on this page:

https://www.zoho.com/mail/help/adminconsole/email-policy.html

I could only set some of these settings however, I'm assuming that is because I'm on the free plan currently...

(Maximum email size & Incoming Maximum emails/minute)

Can you let me know where I can find the information about e-mail limitations like the recipient count, number of outgoing mails, etc. that apply to my free account?
