For setting this option to 50% for shared hosting server is it a good idea or leave it as unlimited?

Reason I ask is we have a limit of 500 emails per hour

But if a customer sends 2 emails and 1 email bounces will get get blocked? just because first email that was sent had 2 recipients?

Hello :)

Per our documentation, this option specifies the maximum percentage of failed or deferred messages that a domain may send per hour. This option only applies after the "Number of failed or deferred messages a domain may send before protections can be triggered" value is reached. Full documentation with examples is available at:

Mail Limiting Features (How to Prevent Spam) - cPanel Knowledge Base - cPanel Documentation

But if a customer sends 2 emails and 1 email bounces will get get blocked? just because first email that was sent had 2 recipients?
The percentage is based on the total messages sent compared to the number of failed or deferred outgoing messages per hour for the domain. You can send a test message that matches the specific example you want to test, and then review the following file to see how it was counted:

Code:
/var/cpanel/email_send_limits/track/$domain
Thank you.
