helo_verify_hosts Type: host list* Default: unset |

For hosts that match this option, Exim checks that the host name given in |
the HELO or EHLO in the same way as for "helo_try_verify_hosts". If the |
check fails, the HELO or EHLO command is rejected with a 550 error, and |

received before EHLO or HELO, it is rejected with a 550 error. |
But that does rather more than just check for HELO-before-MAIL.
OTOH, if you are prepared to use an ACL it is easy. Just check that
$sender_helo_name is set in the MAIL ACL.
