Although the change in my /opt/zimbra/postfix/main.cf are the following;
smtpd_recipient_restrictions = check_recipient_access hash:/opt/zimbra/postfix/conf/protected_recipients,...
same as wrote to RestrictPostfixRecipients - Zimbra :: Wiki
but when i restart postfix with postfix reload command all change related
abount smtpd_recipient_restrictions return default im my main.cf.
Thank you for your relation,
