Does a Redhat 7.3 workstation with KDE have a mailserver on it? I am able to send email from my domain "micmill.res.bgsu.edu" and I am able to recieve from my own domain.

Ex. I log in as root, and send a message from "root@micmill.res.bgsu.edu" to me "mike@micmill.res.bgsu.edu" I am able to recieve that message.

But I am unable to recieve mail from external people to that domain.

Ex. I send my friend and email
I use my personal email address, "mike@micmill.res.bgsu.edu"
He recieves the email, and replies, to it and sends it back to "mike@micmill.res.bgsu.edu"
I never recieve it.

What type of account do I create in KMail?
Local Mailbox
pop3
IMAP
maildir mailbox

and what do I need to enter in the fields?

What you need to check:
* is your domain registred?
* do you have static ip?
If answers are both 'yes', you probably have it working. The type of account usually doesn't matter in this case (but pop3 should be OK, type your IP or hostname as the mail server).
Does your friend get an error when sending mail to you?If not, it's stored (probably on your machine) and you only need to configure that account...

no
yes
no

Basically I don't have a domain, but I do have a static IP. I have sent emails to myself from my yahoo account, and have recieved no errors, so I would assume that my friend has not received errors either.

By a domain I also understand a hostname from your ISP, visible from outside. I understand you have it.

Have you tried configuring Kmail?
