Hi All

I am managing a mail server (midterm newbie).
Server is an Intel Brownsville m/board, 256K Ram.
Clients all using O/Express to get mail of POP server.
Previous version of Redhat 5.2 and 7.0; had a special user group "popuser".
When running userconf I could create my users as "mail only" accounts.
when adding accounts I could select this group as there default group.
Mail "was delivered to there folders" wich they could access from their
Win98 w/stations using
outlook express.
 

You can do something similar with the box by setting up either 
"/bin/false" as their shell
or setting "/bin/rbash" (RESTRICTED shell) and configuring their 
environment with just
the ability to change their password.

The popuser group is'nt present in Linux 8.0 ??

I created a popuser group, and added my users to this group as there default
group.
My users are not receiving mail??. Postmaster(me) is getting error reports :
MAIL UNDELIVERABLE ... reason 553 5.3.5 system config error.
 

By default on RedHat Linux 8.0 Sendmail only listens on 127.0.0.1
Try running "netstat -nap | grep LISTEN | grep 25" and see if there is a 
line in there for sendmail
on either 0.0.0.0 or your LAN NIC address, if not edit 
/etc/mail/sendmail.mc and then follow
the instructions in the comments for both enabling sendmail on the LAN 
NIC and using m4 to
convert your sendmail.mc into a sendmail.cf

Mail is leaving server. Not being recieved by my users.

I am finding the transition from RedHat 5.2 and Redhat 7.0 to version 8.0
extremely frustrating.
...up2date spends +- hour getting RPMS, and then bombs out with bad CRC,
(64k leased diginet line connection).
RedHat had problems today because of their release of the RedHat 9 iso's 
and their
bandwidth was jammed.  You might have better luck tomorrow.  In my 
experience
using up2date is a breeze, and a joy.

...IPOP3 service as registered with XINETD is "off" by default.(Thought I
had solved my prob. when I        found this one.
....The command line network config tools, well where are they. I have
edited (/etc/network) to set
   up address details. (From within XWindows the network config is easy).
What happened to "netconf"
 

Try "neat" instead.  I think it is much better.

Also, take a look at IMAP.
You might like that better than POP.
