It has no view on the users that domain may host for. What you need is to read the spec sections about callouts, in particular around section 39.31 (in manual for 4.50). In addition, you will need to ensure that your INCOMING exim configuration has appropriate routers and transports so that it can actually do the callout (remember, this is done at receiving time). You will probably want to set them verify_only though, to ensure they never get used by a real delivery process (you will also probably have queue_only set). Hope that gives you a nudge in the right direction, Jethro. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
