I've just migrated to Google Apps and it works great, except one little naging thing.
Previously we used CPanel (with Roundcube) to send our mail to each other in the company. But after the switch we try to always use Gmail. But due to different reasons (som unanswered mail etc.) we still have to send some mail via Roundcube. However, if we do this, the mail seems to never leaves the server – it seems like if it checks if the adress belongs to the same domain, the mail never leaves the server but sends it to Roundcube instead of Gmail.
User sends from Roundcube to a @company adress -> email ends up at Roundcube. User sends from elsewhere to a @company adress -> email ends up at Gmail.
Any ideas on how to fix this? To force outgoing mail to always "leave" the server?
