Thanks :-)

Hmm. In the old days there was a finger protocol, but people tend
to turn it off for privacy reasons. Other than that, there is NIS
that's even worse.

The problem with VRFY is that only the number (250, 252, etc.) in
the reply is standardized, but the text that follows is not
standardized at all. It is not required to come from /etc/passwd.

I'm afraid there is no standard service for (username->fullname)
lookup that you could use.

I believe that it is better to have the user configure their MUA
with the correct userdomain email address; note that the email
address is not necessarily related to the login name at all, for
example, I could be sending mail as wietse.venemaporcupine.org.
