I've integrated Roundcube mail (albeit pretty bluntly) in my application.
I.e., I just have it open in an iframe with the login credentials passed through via session variables. It works, but the problem is that it's very slow - and I'm beginning to assume it's because of the iframe thing.
I was wondering if anyone has been able to integrate the program in their own websites in a more efficient way - simply doing an include(index.php) on the program doesn't work obviously.
How can I integrate Roundcube into my app?
Couldn't you use the following plugin as a base for your efforts?
https://svn.roundcube.net/trunk/roundcubemail/plugins/http_authentication/
Let me know if this helps, I'm happy to provide more help/pointers. I'm one of the RoundCube leads.
Cheers, Till
