Using `exim -bt` or `exim -bv` you can verify the routing, that is,
you're checking, if there a chance for a successfull delivery. This
approach works, if your routers are able to verify the existence of a
given user (works for any kind of lookups (passwd, ldap, *sql, …).
verify = recipient
in some ACL asks for "static" verification, that is, it's roughly
equivalent to `exim -bv`. It doesn't help, if you can't do some kind of
lookup.
verify = recipient/callout
checks the routing (probaly quite useless, if you can't access a user
database) and then does a delivery attempt (EHLO, MAIL FROM, RCPT TO,
QUIT) to the final destination.
For ACL testing `-bv`, `-bt` doesn't help. You need
`exim -bhc <sender/ip>`
Best used with swaks:
swaks -f … -t … --pipe 'exim -bhc <sender-ip>'

In your case callout verification probably doesn't work, as long as you
use driver=lmtp, because callouts are done only for *remote* deliveries,
and LMTP isn't considered remote. Though, there is some trick
lmtp_transport:
driver = smtp
protocol = lmtp
socket = /run/dovecot/lmtp # or whatever

We have named acl variables meanwhile: set acl_m_foo = …
