I have a customer that I set up voicemail to email on 3300. They don't have SMTP relay so I have on set up in the cloud. Everything worked fine until I upgraded to 9.0/9.1 software. Now i am getting the error messages in software logs. I have entered a valid sender address and removed the senders address.
CSMTPClientMsg::ProcessResult - Failed sending Voice Mail to Email: From Vpim: test@192.168.55.5 To Mailbox: 290 To Domain: jsmith@computerworks.net File Name: N_V5fa2ae73.0d5.
