We have one requirement where we need to block internal mail communication of our one of the department which contains around 250 mail IDs. Means these 250 mail IDs should not able to interact with each other...for outer world they can.
I used webmail feature to block the mail communication and below command :
zmprov -l ma <original email id > amavisBlacklistSender < list of the rest of the user email id>
But as per webmail , we can only block upto 100 IDs ...is it true ?? is there any setting where we can increase this limit...please confirm..we need this setting..
