Postfix seems to be sending out the database name and prefix

email

I installed Postfix on a Debian LAMP server to allow PHP to send emails from the web applications. I did minimal configuration; I only put in the domain to use when it asked.

The "Message-ID" in the email source contains the name of the database and the prefix used by the tables. This isn't technically a vulnerability, but it's undesirable.

Odd, according to the documentation, the Message-ID should be either YYYYMMDDHHMMSS.queueid@myhostname or queueID@myhostname based on the setting of enablelongqueue_ids. Is this information that's leaking possibly contained in myhostname?
