I have a laptop that I carry around from home to work.
I use Thunderbird Email Client.
Depending on where I am the outgoing smtp server is different.
I can't use the SMTP server of work when I'm home and vise versa.
If I had a third smtp server i might get lucky that it would work in
either location, but no.. not me.

So eventually I change location and I have to change thunderbird's
outgoing smtp server settings... Usually after try to send and get a
message saying I can't connect to the smtp server....
Once for each account.... :(

So when I log is is there a way for the os to know where I am and
tweak these minor differences somehow?
I see under system prefrences, network, locations... but I'm not sure
that take me far enough.. It doesn't setup outgoing smtp
configurations...

From what I hear MarcoPolo might help me.
