I'm wondering if perhaps there's a way to disable logins via the web interface, while continuing to allow IMAP/POP access. I see options to enable/disable logins via POP and IMAP, but none for the web.
The idea here is that I'd like to provide different classes of service for hosted users. At the lowest end, there would only be POP and IMAP access.
I'm currently using the OSS Zimbra 3.0.1 on CentOS.
