Integrating Roundcube mail efficiently - literally - has anybody done it?

Hi guys 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 its very darn slow - and I'm beginning to assume its 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 do开发者_运维问答esn't work obviously...

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
