$ exim -d+acl -bhc 218.234.255.2
and speak SMTP.

Are these callout checks something that you've recently added and only
recently gotten the target system to properly reject? Eg, if you added
the callout checks to an Exchange server, then discovered that you
needed to configure Exchange to reject unknown left-hand-sides, then any
addresses probed before you changed Exchange would be cached as valid.

callout_positive_expire defaults to 24h so these cached false positives
would clear out quickly. See §40.36 of the spec for more details. You
can safely just rm the callout cache db to clear the caches (if callout
caching is the same as every other DB cache in Exim; I've never used
it).
