That's a user agent question.  Some MUAs (Outlook, for example) will
suppress the address@node portion if it finds a "friendly name" in the From:

But suppressing just the @listserv.host.dom part?  That's just asking for
trouble - what will a 'Reply' command do at that point? (Hint - an e-mail
address that doesn't have a @node part on it is by RFC only legal on the
node it's sent on.  Which means that if you're not on listserv.okstate.edu,
and you leave off the @listserv.okstat.edu, there is *NO* legal way to get
the mail to the destination.)

You can probably kinda-sorta kludge it into working with a lot of e-mail aliases,
but only if *every* user is on a machine you control.  So if you have any
gmail or msn or whatever, you lose.  And anyhow, it would be a maintenance
nightmare.

What actual problem are you trying to solve by leaving the @listserv.okstate.edu
off the mail?
