SPLIT Delivery GMAIL AND CWP POSTFIX
« on: June 24, 2022, 12:38:23 AM »
Hello , we are trying to setup SPLIT Delivery using Gmail And CWP email client . We used these guide from gmail https://support.google.com/a/answer/2685650?hl=en#zippy=%2Croute-messages-with-split-delivery

Our goal is to have some emails in GSuite and some email from CWP email client that use one business domain.

Example:
Gsuite Email Accounts
- gsuite1@example.com
- gsuite2@example.com

CWP Email Accounts

- cwp1@example.com
- cwp2@example.com

We tried to follow the instruction from google and we don't have any problem when sending and receiving in Gsuite emails but we got some error / Bounce when sending to emails that using CWP Postfix as email server.


sample@gmail.com -> gsuite1@example.com = WORKING
gsuite1@example.com -> gsuite2@example.com = WORKING
cwp1@example.com -> gsuite1@example.com = WORKING

sample@gmail.com -> cwp1@example.com = NOT WORKING / BOUNCE
gsuite1@example.com -> cwp1@example.com = NOT WORKING / BOUNCE


Check this error screenshot : https://snipboard.io/oK1eZb.jpg


554 5.7.1 <email.com>: Relay access denied



my other settings in cwp mail server
1. Mail Routing  = Remote
2. I added DNS MX records of google to my domain (example.com).


Any ideas how to fix these error?

why not try the simple one

all MX goes to GSuite
then you make filter there

or all MX go to CWP
then set domain forward
