Hello. Does anyone know if client restrictions apply to servers
sending emails to my mail server or just email clients connected
sending email. Is there a way to differentiate restrictions to clients
using eudora or other email clients and restrictions to servers
( another mail server sending email to my mail server. Thanks.

Both. Everything connecting to your "server" is by definition a
"client".

Only if they use different ports. But why do you need that?

"servers sending emails"="clients connected sending email"

smtpd_helo_restrictions : restrictions to helo string, sent by client
smtpd_client_restrictions : restrictions to client host name
smtpd_sender_restrictions : restrictions to sender's email adress
smtpd_recipient_restrictions : restrictions to restrictions's email
adress
smtpd_data_restrictions : mail body restrictions
smtpd_end_of_data_restrictions = END-OF-DATA command restrictions

ot it very easy but no so ovious

just black list emails like j...(a)somedomain.com or the whole domain
after the sas auth in the senders policy

smtpd_sender_restrictions =
permit_sasl_authenticated,permit_mynetworks,check_client_access
hash:/etc/postfix/spoof_access,check_sender_access hash:/etc/postfix/
spoof_access
