Voicemails sent using the "email_to" button do not use the configured from address

What I did:

• Logged into the "User Portal";
• Selected the "Voicemail" link at the top left;
• Checked one of the listed voicemails;
• Entered an email address in the field following the "email_to" button;
• Pressed the "email_to" button.

What happened:

• The email with attached voicemail was delivered, BUT the "from address" was "asterisk@localhost.localdomain" - not the value configured in the "serveremail" setting in "/etc/asterisk/vm_general.inc".

This came to our attention because the address was not in our whitelist and the emails were not received. We have added "asterisk@localhost.localdomain" so the immediate problem is fixed.

It would be more consistent and predictable if this feature would either honor the "serveremail" setting from "/etc/asterisk/vm_general.inc" - or provide some other means of adjusting the from address.
