I recently created a standard exim config file for "service
machines", i.e. those that do not generally handle user mail. Part
of this is that any outgoing mail for a "system account" always
comes from a fixed local part @host.le.ac.uk, and mail from "user accounts"
come from local part @le.ac.uk.
The definition of "system" account in debian is uid < 1000, so I
use the following macro:
Is_SysAcct = ${if <{${extract{2}{:}\
{${lookup passwd {$local_part}{$value}{0}}}}}\
{1000}\
{1}{0}}
You can then use it in something like (this is a rewrite rule, of
course you need it in an ACL instead).

(It's a shame macros cant have arguments, in some way, otherwise I
could see that becoming Is_SysAcct($local_part) rather than having
to be hard-coded into the macro definition.)
