postfix discard

[five04tluv]

I've been using postfix_custom_header_checks to discard emails to certain users. Unfortunately this discards the ENTIRE message. I see that in postfix I would need to use transport_maps to

Code: Select all

/etc/postfix/main.cf: 
    transport_maps = hash:/etc/postfix/transport 

/etc/postfix/transport: 
    someuser@domain.com	discard:
    someuser2@domain.com discard:

How do I do this the Zimbra way?

current postconf transport_map usage

address_verify_transport_maps = $transport_maps
transport_maps = proxy:ldap:/opt/zimbra/conf/ldap-transport.cf (which does LDAP lookup for destination mail server for user)

Hello,

Please see the following steps to use tranport_maps in Zimbra (I've tested it in 8.7 and 8.8):

su - zimbra

vim /opt/zimbra/postfix/conf/transportfile

(edit the file with your discard rules)

zmprov mcf zimbraMtaTransportMaps "lmdb:/opt/zimbra/postfix/conf/transportfile,proxy:ldap:/opt/zimbra/conf/ldap-transport.cf"

I'm on NE 8.7.11, I don't have a dir /opt/zimbra/postfix and I don't see any mention of this in the Admin Docs.

Hi,

The correct path is: /opt/zimbra/conf/

So the steps would be:

vim /opt/zimbra/conf/transportfile

(insert your discard rules)

postmap /opt/zimbra/conf/transportfile

zmprov mcf zimbraMtaTransportMaps "lmdb:/opt/zimbra/conf/transportfile,proxy:ldap:/opt/zimbra/conf/ldap-transport.cf"

Postfix will reload with the new rules within a few minutes, but you can force the reload with "postfix reload"
