Resolution


1. Create a file:

vim /opt/zimbra/postfix/conf/prepend_header.re

append the line:

/(.+)/          PREPEND X-Envelope-To: $1

2. Add the following line in /opt/zimbra/conf/zmconfigd/smtpd_recipient_restrictions.cf

check_recipient_access pcre:/opt/zimbra/postfix/conf/prepend_header.re

It should look like:

%%contains VAR:zimbraMtaRestriction check_client_access lmdb:/opt/zimbra/conf/postfix_blacklist%%
%%contains VAR:zimbraServiceEnabled cbpolicyd^ check_policy_service inet:localhost:%%zimbraCBPolicydBindPort%%%%
check_recipient_access pcre:/opt/zimbra/postfix/conf/prepend_header.re
reject_non_fqdn_recipient
permit_sasl_authenticated
permit_mynetworks


3. Finally restart:

 zmmtactl restart;zmmailboxdctl restart;zmconfigdctl restart

Beware, that this solution breaks the privacy of Bcc recipients.

There is also a bug opened for that here.
