two smarthosts in exim?

[Jiri Baum <jiri@baum.com.au>]

Hello,

is there an easy way to give two smarthosts to exim?

I use two ISPs alternately, and I need to use the correct smarthost for
each (anti-relaying measure). If the wrong one gets used by mistake, mail
returns to sender as rejected.

Should I:
  * set something in exim.conf (that I missed the first time), or
  * have a script edit exim.conf, or
  * make an alias for the mailserver (say smtp.baum.com.au) and change it
    appropriately, or
  * something else?

I'm doing this as the admin, BTW, not as a package.


Thank you
