[plug] Linux Mail Server?

[Jon Miller]

If using Novell NetWare 5 or 5.1 TCP/IP is the native protocol.  All my NetWare sites are using Linux as the Internet Gateway as I never allow any server NetWare or NT to be close to the Internet.  We use IP as the native protocol and IPX is only used if there is an application that is needed.  To be perfectly honest both NetWare and Linux are extremely stable I have in our office 2 of each and they only come down when I bring them down (finally got rid of my NT server).  They are setup as follows:
1 NetWare 5.0 (main file and print & GroupWise 5.5 plus WebAccess (GroupWise web-based email)
1 NetWare 5.1 (monitor server, allows me to browse in from outside to check on my NetWare servers)
1 Debian Server (Internet Gateway (Firewall and Web Server)
1 Linux Red Hat 7.1 (Monitors clients Linux servers)

Desktop
Mine - W98SE and Mandrake 8.0 dual boot
Test Desktop (Win2KPro)
Everyone else Win98SE
E-mail client GroupWise 5.5 and Outlook 2K)

Actually, if the network is small, then there may be merit in leaving
netware as it is. You can use more than one protocol on a network at a
time, so IPX and TCPIP can both co-exist happyly.

Set the gateway box up to understand TCPIP only (don't compile IPX support
into the linux kernel). Have it do mail using postfix and fetchmail.

With this setup, it is less likely someone on the outside will be able to
access files stored on the netware server (if the linux box becomes
comprimised). Anyway, if you have netware up and going already, why get
rid of it.
