Just got Zimbra up and working on a CentOS 4.2 box. Web interface looks very nice and is pretty snappy performance wise except for the initial log in. Some questions.

1) I can receive and send mail just fine with a Thunderbird mail client, but I cannot send mail (although I can receive it) with K-mail. It complains of either a wrong password (which is not the case) or an unsupported authorization method. I have tried all of the authorization methods availabel in k-mail to no avail. My settings in zimbra are as follows:

Global => MTA authentication enabled dns lookups enabled
Global => POP not enabled (I'm using IMAP)
Global => IMAP enabled SSL for IMAP enabled clear text login enabled


Servers => MTA enabled TLS authentication only not enabled
Servers => IMAP enabled SSL for IMAP not enabled clear text login enabled
Servers => POP not enabled

2) Is it possible to use KOrganizer (Kontact) as a client for the Zimbra calendar service? If so, are there instructions somwhere?

3) Is it possible to use the Zimbra web interface to access POP or IMAP accounts on other servers?

Thanks.
