RE: Mail Server - Sendmail + IPOP3

["Gavin Mellors" <gavinjm ComparexAfrica co za>]

Thanks for that Info w.r netstat, Ben, will try it.
Will seek out "neat" as well.

With regards IMAP, I did consider it, but how do I set up my outlook
express clients to receive there mail using IMAP ?
Under my clients O/Express->Account settings->Connection->server
types->incoming server: only "POP3" (PORT 110) option is availible
Does IMAP also use port 110 ??

I am using SWAT to manage my samba installation, what a pleasure.
On my RedHat 7.0 installation I had "Inflex" mail scanner/mimeripper
installed, also a pleasure
to work with.

Regards
Gavin

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.

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

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.

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

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