I am trying to configure Asterisk (running on AstLinux) to send emails when it receives voicemails through GMail's SMTP server, but it is not working. I do not receive any emails, and I get the following error in the Asterisk system log:

Dec 14 02:02:56 donald msmtpqueue: Mail system is stopped. Use 'msmtpqueue' to display the mail queue.

These are my configuration files (my server is located at


## SMTP Mail Relay
## This is the SMTP server that all mail from cron, etc. on this
## system will be sent through.  This includes Asterisk VM notifications.
## The username and password for communicating with the SMTP server.

What is msmtpqueue output? Do you have any other mail related messages in the logfile? – ouranos Dec 14 '11 at 4:02
msmtpqueue outputs the formulated email queue, but nothing else. There are no other messages related to emails in the log file. – nickb Dec 14 '11 at 4:14
Try to manually flush the queue: msmtpqueue -f – ouranos Dec 14 '11 at 4:32

From the web interface of Asterisk, I had to modify the SMTP settings in the Network tab, instead of editing the rc.conf configuration file. Once I made the changes under "Outbound SMTP Mail Relay" on the Network tab and rebooted the machine, Asterisk cleared the message queue and pushed all of the queued emails out.
