           Summary: $host is empty on a verify callout
           Product: Exim
           Version: 4.82
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Transports
        AssignedTo: nigel@???
        ReportedBy: Claas.Hilbrecht@???
                CC: exim-dev@???

To reproduce this issue setup a transport with:

hosts_require_auth =
hosts_require_tls =
hosts_verify_avoid_tls = *

You also need a auth provider that does a host lookup like:

${lookup sqlite {/etc/exim4/sqlite.db SELECT password FROM auth_server WHERE
username='${quote_sqlite:$auth1}'}{$value}fail}

If the transport is used for mail delivery everything is fine. But using the
transport to verfiy a recipient the $host variable is empty.
