[exim] multiple delivery locations for

Hi.

I have a question about exim configuration.

Let's say that I have users local mail stored in one of two locations --
/var/mail or /local/mail. When mail is delivered, I can't just specify
the default "file=/var/mail/$local_part" under "local_delivery". How
might I look up which file to deliver to from a file ordered something
like this:

user1 /var/mail/user1
user2 /local/mail/user2

etc...

Thanks,

Jason.
