on exim 4.xx I would say:
if you want to check wether the user exists on your local machine you should
have this in your ACL (you should have this already...)
accept domains = +local_domains
endpass
message = unknown user
verify = recipient
If you want to check the recipient on the remote mailserver,
you could do a callout (you are relay for blah.example.com):
accept domains = blah.example.com
endpass
message = unrouteable address
verify = recipient/defer_ok/callout=10s/callout_defer_ok
Mit freundlichen Grüßen
