sendmail on a laptop

[Trevor Smith]

I run FC2 on a laptop and I'm playing with sendmail for various reasons. 
Currently I send through one of two ISPs' SMTP servers: either my web/email 
hosting provider's, mail.haligonian.com, when I'm at school or my local 
ISP's, smtp1.ns.sympatico.ca, when I'm at home.

I can not use the home server when I'm at school (and not on sympatico's 
network), nor can I use my haligonian.com server when I'm at home (don't know 
why, it just fails). This is a pain in the butt, naturally, that I have to 
manually switch SMTP servers every time I move the laptop between locations.

I finally figured out how to get sendmail to send mail -- at home -- using 

define(`SMART_HOST',`smtp1.ns.sympatico.ca')dnl
and
MASQUERADE_AS(ns.sympatico.ca)dnl

I haven't tried this at school yet, when I have traditionially had to use 
mail.haligonian.com but I'm guessing that when I'm there, sympatico will deny 
me use to their servers.

Does anyone have any advice on a simple, no manual intervention way to send 
email from a laptop regardless of network that I'm attached to?
