Hello everyone. Thanks for reading this post. I hope I can get some help about this as my 3CX partner and I have been trying to resolve the problem for almost 2 months now. We have V11 running on Windows 7 Pro. It has been configured with our email server and address in the Settings / Mail Server tab. With the current setup we can send Welcome emails and also users can receive voice mails delivered to their email. However the problem is when we send fax it does not get delivered. We can see that the fax transmission was successful. Any help you can provide will be much appreciated as this is the only issue that is holding us back from going live on the 3CX pbx. I would also like to request SSL / TLS authentication as many service providers now require this.
