In My setup I have configured multiple DL , domain permissions / restrictions by using below mentioned list :
RestrictPostfixRecipients - Zimbra :: Wiki
Restrict users to certain domain - Zimbra :: Wiki
Restrict sending to certain domains - Zimbra :: Wiki
And all postfix rules are working very fine without any issue.
Now my customer's new requirement is as below :
They have around 150 shop email IDs. and all are added in email@example.com DL.
Now customer want all shop IDs should not able to send mails within a same DL members. means none of the shop ID should send mail to other shop ID.
I have checked forum and wiki pages...every where details are how can we put ALLOWED domain / email ID and restricted DOMAIN ....I couldnt get details how to mentioned RESTRCITED EMAIL ID.
