Usually it's the reverse: you set it so that your ISP's SMTP server
accepts your mail as coming from a valid Internet domain.  As in the
case where your mail server is itself not permanently connected (a
dialup), and has a "made up" domain name.

Yours is probably already a valid domain, and 'qualify_domain' was set
to something invalid.
