Why are you making your life so complicated?
Why are you trying to make a workstation behave like a server? I.e. why
are you running an MTA on your workstation?!?!?
Why don't you do what everyone else using "mobile" workstations does and
always set your MUA to use the SMTP gateway appropriate for the ISP you
connect to? If you find that to be too difficult then you don't have
properly integrated software. If you can't do that software integration
yourself then I would suggest finding an appropriate pre-integrated
software platform to use, such as Mac OS-X. My colleagues who use
laptops all use Mac OS-X now and they seem to have no problem using any
old network they plug into -- it only takes them a moment or two to
configure their settings (usually it's one pull-down menu choice from
the network icon on their menu bar) and everything "Just Works(tm)".

It is a trivial patch indeed, at least from my perspective, but I don't
have one to offer since I don't have any clue what dhclient software you
use, and it's almost certainly not the same as what I would use. :-)

Then what the heck are you doing fiddling with third party networks that
don't let you use SMTP!?!?!?
Keep your workstation connected to your own network when you're doing
things internally and you won't have any problems. :-)
Or are you trying to tell me you're trying to run a 600 user mail domain
on a server that's connected only by some mass-market "home PC" service?

I hope you got that backwards. Adding a new service, especially a
"premium" service which bypasses certain limits on the base service,
should _attract_ customers, at least if there's any clue amongst any
percentage of the potential customer base, provided of course the
additional charge for this added service is within reason for the
market.
