Plus Addressing is a feature that allows a sender to append a tag to the user id of a recipient. This lets the recipient more easily sort the incoming mail using a mail filter.

For example, user@zimbra.lab could also be reached using the address user+tag@zimbra.lab.

To enable Plus Addressing with Zimbra, use zmprov as follows:

zmprov mcf zimbraMtaRecipientDelimiter +

Note that the delimiter can be a character other than '+'.

To disable Plus Addressing, use zmprov as follows:

zmprov mcf -- -zimbraMtaRecipientDelimiter +

After making changes to enable or disable this feature, you can restart the postfix service :

zmmtactl restart

And check that the postfix configuration has the right value :

postconf recipient_delimiter
recipient_delimiter = +

Disable addresses

If you want to disable a specific address, e.g. because it has been targeted by spam, you can enable a postfix recipient and client restriction map.

Create the postfix recipient access file:

touch /opt/zimbra/conf/postfix_recipient_access

Edit the file to include the address:

user+spam@zimbra.lab 550 User Unknown

Build the lmdb file:

postmap /opt/zimbra/conf/postfix_recipient_access

Enable check_recipient_access and restart postfix:

zmprov mcf +zimbraMtaRestriction "check_recipient_access lmdb:/opt/zimbra/conf/postfix_recipient_access"
zmmtactl restart
