[Freeswitch-users] Changing From header in voicemail to e-mail notifications

We see FreeSWITCH mod_voicemail in the From header of the voicemail to e-mail notifications. We also want to change the E-mail address in the From header to come from a specific domain. How do we go about changing the From: header in the voicemail to e-mail notifications? We do not want FreeSWITCH mod_voicemail to appear in the From header of the e-mail messages.
