I'm not a complete Linux beginner, but this is something that's tripped me up. What's the minimum needed for one user on a machine to send email to another user on the same server? I have a home FC4 box, and login using different id's for different purposes. I'd like to be able to send an email from one userid to another. I'd rather not have to setup Sendmail, but is that or another MTA what's needed?
