Multi-Homed Computers
A multi-homed computer is a computer with one or more network cards. The advantage of running WorkgroupMail on a multi-homed computer is that it provides greater security when the
computer is connected to the Internet. For instance, if WorkgroupMail is run on a single network card computer, when the computer is connected to the Internet, in the absence of a firewall, the local
POP3 and SMTP server that WorkgroupMail provides for the local e-mail clients, for sending and receiving mail, will be available to anyone on the Internet. With a multi-homed computer, you can
instruct WorkgroupMail which interface(s) (network cards) it should make the local POP3 and SMTP servers available on.
You can do this by clicking the Settings button in the shortcut bar and selecting the Interfaces page.

This page lets you identify the internal and external networks to WorkgroupMail.
If you are running WorkgroupMail on a multi-homed computer, you will be automatically prompted for the interface on which local clients will connect (i.e. the internal interface) when you run
WorkgroupMail for the first time.
