Hybrid Mail Google vs Zimbra Error "Sender address rejected: not logged in"

Postby lazida » Sat Jul 02, 2022 9:29 am

Hello. I configuring Hybrid Email Zimbra vs Google Workspace. (Zimbra 8.8.15)

MX point to Google, User does not exist on Google will transport to Zimbra (catchall)

When have email, if user does not exist on google workspace will catchall to mail server.

On Zimbra server, I already config "Enforcing a match between FROM address and sasl username" to security
https://wiki.zimbra.com/wiki/Enforcing_ ... ername_8.5

Because this config, so When email transport from Google workspace to Email server denied "Sender address rejected: not logged in"

I can't turn off config "Enforcing a match between FROM address and sasl username" because Security Rule. So how can I config allow to using hybrid email?

Any extra config can resolve this issue?

Note:

Internal email from Zimbra to Google (work oke)
Internal email from Google to Zimbra (Sender address rejected: not logged in)

Email from internet to both User host on Zimbra and Google (work oke)

Thank!!
