I would not consider this as a bug. It's fully configurable and the
default is
smtp_banner = $smtp_active_hostname ESMTP Exim $version_number $tod_full
reeceived_header_text = Received: ${if def:sender_rcvhost {from
$sender_rcvhost\n\t}{${if def:sender_ident {from
${quote_local_part:$sender_ident} }}${if def:sender_helo_name
{(helo=$sender_helo_name)\n\t}}}}by $primary_hostname ${if
def:received_protocol {with $received_protocol}} ${if def:tls_cipher
{($tls_cipher)\n\t}}(Exim $version_number)\n\t${if def:sender_address
{(envelope-from <$sender_address>)\n\t}}id $message_exim_id${if
def:received_for {\n\tfor $received_for}}
and is probably even documented.
It's up to you to change it.
Best regards from Dresden/Germany
