I saw owncloud is working on a built in mail client. I was wondering if this may end up being a default instead of roundcube. Since we are using it for calendar and contacts. Seems like a good move to have full integration of mail, contacts and calendar.
As I pointed out in the issue above I believe it can only be of mutual benefit to cooperate with ownCloud and drive the integration of their Mailclient forward.
Maybe this can even be a milestone, even if it might turn out to be almost a blocker. But that’d be worth it.
