    # Someone is trying to spoof a domain on the server
    deny condition = ${if match_domain{$sender_helo_name}\
    message = Forged HELO: you are not $sender_helo_name
    log_message = Forged HELO: $sender_helo_name Spoof Attempt

    I've had this as one of my acl_smtp_helo = check_helo rules in Exim for months, but now it is causing squirrel to get blocked when trying to send.
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...
