When so used, yes - in 'verification mode'. Per the docs.
A router verification run is the natural and 'automagic' way. It inherently
insures that what is accepted is what is deliverable.
But if you have even ONE 'leaky' router (i.e. catchall, accept
everything/anything) then you need to either exempt that router from being used
for verification (look for 'no_verify')

Why would you want Exim - which can reject bogus traffic *during* the smtp
session and avoid bounce backscatter - to onpass garbage to Cyrus - which cannot?

All the information you need to clean up your configuration is in (both) the
Exim 'main' documents, and the Debian-specific ones.
