Need to Understand the real differences

[Multisites]

Hello,

I need someone to help me to understand, within /etc/postfix/main.cf file, the real differences between these elements below, and when should I use one or another:

1) The difference bettween:

stmpd_client_restrictions
stmpd_sender_restrictions
stmpd_recipient_restrictions

2) And specifically within smtpd_recipient_restrictions, the differences between:

check_client_access hash:
check_sender_access hash:
check_recipient_access hash:

Thank you very much.

Mario Lima./
