Outbound mail is rejected because the "from" address is "1000@localcomputername". Voicemail messages are sent using the sendmail command. The mailer is actually postfix. I have set vm_mailfrom and email_from both to "workingmail@realdomain.com" both in conf/directory/default/1000.xml and conf/autoload_configs/voicemail.conf.xml. I have changed the voicemail.tpl so it has the literal, correct sender address. I have tried to change the "mailer-app-args" in conf/autoload_confings/switch.conf.xml to include a " -f workingmail@realdomain.com ". All of this is ignored, and "1000@computername" appears as the from address in the rejection notices. Can anybody point me to the correct way to set the "from" address so it is actually applied to outbound emails? The sendmail command works fine from the command line. This is my first post. Let me know if I am not following the rules. Thanks, Roger Young
