I have just installed Zimbra Toaster on to my XP Pro machine but I keep getting the following timeout error:
WebException: Timeout
The Operation has timed-out.
at System.Net.HttpWebRequest.GetRequestStream()....

I have checked the Zimbra logs but I am unable to find anything regarding this issue.

The Timeout seems to occur when the Seccure Connection is checked and if I uncheck it then the Toaster does not seem to do anything (no mail notification etc).
