From dir-spec.txt [1]:

"A router is called an 'Exit' iff it allows exits to at
least two of the ports 80, 443, and 6667 and allows exits to at
least one /8 address space."

So that means that your relay gets Exit flag (and thus exit probability)
only if it's able to exit as described above. Though if your realy (OR)
can exit (ExitPolicy is not set to `reject *:*`) and has no Exit flag
there may be some non-standard actors that can use your relay to exit.

tl;dr ExitPolicy == exit traffic allowed, Exit flag == (confoming) clients
can use your exit.
