Subject: Where does the hostname in the To/CC files come from?

I'm running Pine 3.96. When 'To' or 'CC' addresses are displayed, they
include the mailserver hostname. If I enable viewing of expanded
headers, the 'To' and 'CC' addresses don't have the host name. In fact,
the addresses that cause problems have no [email-masked]' portion at all.
When a mail address does have a fully qualified domain name, the
mailhost name dosen't get appended.

Is there a configuration parameter available to fix this or is this some
type of bug?
