User or admin, likes to forward all incoming emails thats going to one account to multiple recipient.


Redirection based on sender address

In this example, emails send from user@domain.com will be trapped and sent to user_trapped@domain2.com. We are using check_sender_access to achieve this.

  • Enter following in the file /opt/zimbra/conf/postfix_recipient_restrictions.cf Make sure it is entered at the top of the file.
 vi /opt/zimbra/conf/postfix_recipient_restrictions.cf

Zimbra 8.5 or above:

check_sender_access lmdb:/opt/zimbra/postfix/conf/restricted_senders

Zimbra 8.0.9 or earlier:

 check_sender_access hash:/opt/zimbra/postfix/conf/restricted_senders
  • Create a file /opt/zimbra/postfix/conf/restricted_senders and list all the users, whose emails you want to redirect.
 cat /opt/zimbra/postfix/conf/restricted_senders
 user@domain.com REDIRECT user_trapped@domain2.com
 user2@domain.com REDIRECT user2_trapped@zbc.com
  • Create the hash and restart postfix.
 postmap /opt/zimbra/postfix/conf/restricted_senders
 zmmtactl restart 


Login as user@domain.com and try sending email to any address. It will be redirected to user_trapped@domain2.com account and the log entry should look like this in /var/log/zimbra.log

 Apr 12 10:08:34 mta postfix/smtpd[521]: NOQUEUE: redirect: RCPT from domain.com[xx.xx.xx.xx]: <user@domain.com>: Sender address triggers REDIRECT 
 user_trapped@domain2.com; from=<user@domain.com> to=<realrecipient@domain.com> proto=ESMTP

Sender BCC Maps

In this example, we need a copy of all emails sent FROM user@domain.com to bccuser@domain.com user. I am using sender_bcc_maps.

  • Enter following line at the end of file /opt/zimbra/postfix/main.cf file.

Zimbra 8.5 or above:

sender_bcc_maps = lmdb:/opt/zimbra/postfix/conf/sender_bcc
recipient_bcc_maps = lmdb:/opt/zimbra/postfix/conf/recipient_bcc

Zimbra 8.0.9 or earlier:

sender_bcc_maps = hash:/opt/zimbra/postfix/conf/sender_bcc
recipient_bcc_maps = hash:/opt/zimbra/postfix/conf/recipient_bcc
  • Create a file /opt/zimbra/postfix/sender_bcc and add the sender address and forward address in following format. You can enter a list of users.
cat /opt/zimbra/postfix/sender_bcc
user@domain.com  bccuser@domain.com
  • Create the hash and reload the MTA.
 postmap /opt/zimbra/postfix/conf/sender_bcc
 postmap /opt/zimbra/postfix/conf/recipient_bcc
 zmmtactl restart


Send an email from user@domain.com and check the logs in zimbra.log. You should see two send entries, one for user@domain.com and other for bccuser@domain.com
