Just ran across an issue after updating a while back to 5.0.18 involving my
Distributions lists and Postfix restrictions I had set up where I could now send from external. Ok, so I remove the files I had originally setup - which were still there - in my /opt/zimbra/postfix/conf/ directory:

permitted_senders
permitted_senders.db
protected_recipients
protected_recipients.db
update_protected_recipients

and go thru the 'RestrictPostfixRecipients' wiki doc
and follow steps to the letter (Just like I did in 5.0.6) including adding in my main.cf the
'permitted_senders_list ='
(which was still listed there but was named as 'permitter_senders_list =' (?))
Restated postfix and I even restarted Zimbra with no result for blocking external e-mail to my Distribution lists I had defined in protected_recipients file. I know it probably is something very simple I missed buy not able to find. Even went trough process twice with same results.

Note: Long story about 'mynetworks'-Basically person in office with a Verizon Smartphone and getting POP3 access to that darn thing......
My Steps:
Code:
zimbra:~ # su zimbra
zimbra@zimbra:/root> /opt/zimbra/postfix/conf/update_protected_recipients
rebulid permitted_senders file...
rebulid protected_recipients file...


zimbra@zimbra:/root> postfix reload
postfix/postfix-script: refreshing the Postfix mail system
zimbra@zimbra:/root>
Zmcontrol restart (stop/start) here also.....
