Why does Roundcube use a custom implementation of an IMAP client?

Hello!

I was wondering why Roundcube uses a custom implementation of an IMAP client instead of using php_imap. Did the developers have problems using the PHP extension?

Cheers,

Because we didn't want to be limited, and it was proven in the past that our implementation was just faster.

Plus php_imap is often not install on servers.
