When my users try to attach a wav file (comes from our voicemail system if it matters), they get a SOAP Fault error. I've been able to duplicate this using the Outlook connector and the web client.

Error message follows:
Could not send message: mail.SEND_FAILURE

msg - SMTP server reported: null
code - mail.SEND_FAILURE
method - ZmCsfeCommand.prototype.invoke
detail - soap:Sender
data - [object Object]
Can anyone help me figure this one out?


We're using ZCS Network Edition 4.5.10.
