software for sending mail XENIX to DOS pc's

[Brooke King]

A friend has a couple of SCO XENIX AT's (a '286 and a '386). 
He'd like to send e-mail over phone lines to associates who don't
want to change from using DOS.  Is UUCP available for DOS
(stranger things have been true!)?  Are simple file transfers the
way to go?  Suggestions?
