Plus Addressing
Plus Addressing
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 = +
