Migrating an existing domain's users to Google for Domains
 
Hi all:

I have several clients, who are moving email services off of the ISPConfig hosted server to google for domains. They were using the accounts provided by ISPConfig, and many of them have crontabs, shells, admin rights etc, so I can't delete them.

However, they also have the original user@domain.com email addresses setup in Postfix's virtualuserstable. When a webapp, the system, etc try and email these users, Postfix sends the message to the local Maildir instead of looking up the new MX and sending the mail onword.

I don't see a clear way to fix this in the web panel. I can't edit the postfix files, since ISPConfig will rewrite them. Do I need to manually modify the database for this level of customization? Is there a better way?

More details upon request..

Please select "External Mailserver" on the Options tab of each affected Co-Domain.

Hey Falko.

Thanks for pointing me towards the external domain. I selected external mail server for
domain.com (which is using gmail), and left internal mail server for
store.domain.com.

The users at store.domain.com have .forward files to forward to user@domain.com

However the entries for user@domain.com are still in /etc/postfix/local-host-names and /etc/postfix/virtualusertable even after restarting ISPConfig. Shouldn't they be removed?

Did you set domain.com to "External Mailserver" or maybe www.domain.com?
Go to the domain.com Co-Domain in ISPConfig; then on the Options tab of the Co-Domain, select "External Mailserver".
