They shouldn't have to if the setting is static for the network you're
connecting to -- i.e. not dependent on the particular subnet your
address is assigned at any given time.

That's only because your system integrator (you? :-) did a very poor job
of integrating Exim and/or the DHCP client software into your system.
If the DHCP server is advertising MX hosts then it should be trivial to
have the dhclient software set the right gateway for Exim to use.

"if ..."? What does this have to do with anything?

You lost control the moment you agreed to use the network which blocks
port 25 -- bypassing their rules could very well get you in a great deal
of trouble, especially if it's a company network with a security policy
that mandates all e-mail go via authorised company gateways.
If you want this kind of freedom to manage your own SMTP services than
you've got to pay for the privilege. I.e. find an ISP who will accept
your good money to allow you to do what you wish.
