We have recently installed Zimbra and are experiencing problems with our Blackberry devices using IMAP. We are able to send email but we are not able to receive any email on the Blackberry devices.
We are using a signed SSL certificate and not a commercial one. Would this be an issue. I am able to send and receive email on my droid but we are having problems with receiving email on our Blackberry devices.
If you have any insight into this issue please let me know.
