Block user to send email locally or externally
Problem
How to block users to send email locally or externally.
Solution:
1). Open file /opt/zimbra/conf/zmconfigd/smtpd_sender_restrictions.cf and add this line at the top
%%contains VAR:zimbraMtaSmtpdSenderRestrictions check_sender_access lmdb:/opt/zimbra/postfix/conf/restricted_senders%%
Then execute :
zmprov ms `zmhostname` +zimbraMtaSmtpdSenderRestrictions "check_sender_access lmdb:/opt/zimbra/postfix/conf/restricted_senders"
2). Open file /opt/zimbra/conf/zmconfigd.cf and add those lines before "RESTART mta". This is example on my system
POSTCONF smtpd_restriction_classes local_only POSTCONF local_only FILE postfix_check_recipient_access.cf RESTART mta
3). Create a file /opt/zimbra/conf/postfix_check_recipient_access.cf and add the following line
check_recipient_access lmdb:/opt/zimbra/postfix/conf/local_domains, reject
4). Create a file /opt/zimbra/postfix/conf/restricted_senders and list a user which you want to block. Follow this syntax :
user@yourdomain.com local_only
5). Create an empty file /opt/zimbra/postfix/conf/local_domains, here we list all the domains where restricted users allowed to send mails. But we will keep this blank file as we don't want to send emails inside or outside from this id. Following is the command :
touch /opt/zimbra/postfix/conf/local_domains
6). Run following commands
postmap /opt/zimbra/postfix/conf/restricted_senders postmap /opt/zimbra/postfix/conf/local_domains zmmtactl stop zmmtactl start
