I have a Zimbra 8 ZCS Open Source Edition Gmail's Sync configuration on Ubuntu 12.04. I configured the /opt/zimbra/conf/relay_password file:
If I try to add another line for another account I got this message: "postmap: warning: /opt/zimbra/conf/relay_password.db: duplicate entry: "smtp.gmail.com:587"
But if I try to send an email with that only line all the accounts send from firstname.lastname@example.org
Can I configure a different relay_password file for each account?. Like relay_password1, relay_password2, etc?
Or what you suggested me to do?
