Yes, but the check happens at the beginning of an SMTP session, not
in the middle. A Postfix process does not reopen files mid-flight
because it may not have sufficient privileges to do so (iin addition,
cdb files are renamed, not overwritten, so the lookup result does
not change during the lifetime of the SMTP daemon process; if you
need instant visibility, use LMDB, LDAP or *SQL).
