Hi there,

Is there a way to monitor the mail queue so I can view what the mailer is doing? I have root access to my servers.

Use case: I perform a monthly mailing to approximately 10K addresses. Fairly consistently (about 80%) of the time the mailing process "hangs" and I can not figure out how to "see" what's hanging things up. I have to reboot my server to get the mailing going again. No messages are written to the Drupal logs, to /var/log/messages or to the httpd log. It's a real mystery and I am looking for advice on how to debug this.

Is there an internal log I can tail while the mailing is running or is there a log I can review to determine what is hanging the mailing.

Once I reboot the mailing continues when cron executes: I am receiving the following message after each cron run:
Array
(
    [is_error] => 0
    [version] => 3
    [count] => 1
    [values] => 1
)

But the mailing will still be "locked up" until I reboot the server.

Thanks in advance!
