Ken:
If I understand correctly you want to find the ip address of a dynamic ip.

I got htis grotty little line from a book called "Linux Network Toolkit".
It returns the ip address from ifconfig. It is likely, that someone who
can program perl (I can't) could have this script run from within exim and
get you an IP address.

ISP_IP=' ifconfig ppp0 | grep 'inet addr' | awk '(print $2)' | sed -e
"s/addr\://" '

as all one line. It pipes the output of ifconfig to grep which gives you
the line with the ip address. SED strips out the text 'addr:' leaving
the ip . I have not tested this.
