I am looking at Zimbra to replace my email hosting services, and for a start I am looking at the Open Source version.
I have got it all set up, and it recieves email fine, however, the interface in several different browsers (Linux Firefox, Mac Firefox, Mac Safari, etc) all throw up an error when I try to send an email:
A service error has occurred.
msg - system failure: MessagingException
code - service.FAILURE
method - ZmCsfeCommand.prototype.invoke
detail - soap:Receiver
Please can anyone help?
