My zyxel router automatically connects to the net whenever it needs
to send a packet off the local lan. The router then gets a dynamic
address and uses a form of network address translation that zyxel calls
SUA to hide the internal network. Currently the only way to get the ip
address is through a telnet or serial connection to the router. I think
expect would let me navigate through the menus to get the ip address
automatically, but the address would only be valid when the isdn line is
up. If I send mail while the line is down, the mail itself brings the
line up. This is too late to modify the message.
I really like your idea. I've had quite a few problems getting local
and remote mail to work with smail and a dialup connection.
