# mgenmid(1)

generate a Message-ID

## NAME

**mgenmid** – generate a Message-ID

## SYNOPSIS

**mgenmid**

## DESCRIPTION

**mgenmid** generates and prints a unique Message-ID. The Message-ID consists of an encrypted timestamp, a random value, and a fully qualified domain name.

The fully qualified domain name is arrived at by:

1. Using ‘FQDN:’ from *${MBLAZE:-$HOME/.mblaze}/profile* (if set).

2. Resolving the current hostname.

3. Using the domain component of the mail address in ‘Local-Mailbox:’ from *${MBLAZE:-$HOME/.mblaze}/profile* (if set).

If these steps don't result in a fully qualified domain name, **mgenmid** fails.

## EXIT STATUS

The **mgenmid** utility exits 0 on success, and \>0 if an error occurs.
