I have domain1.com configured in Google Apps for the email server. Recently the company changed its name to domain2.com, and that new domain was added as an alias for domain1.com in Google Apps.
If the emails are sent from the web interface, its really easy to change the "send email from" to use the alias all the time. The problem is that all the employees use BlackBerry devices. Is there a way to configure those devices to send the emails from @domain2.com by default?
