[exim] configuration Received?

Hello all.

I try to change (i little bit) Received headers in my exim, it changed but
strange. In configure i wrote:

received_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\
${if def:sender_address \
{(envelope-from <$sender_address>)\n\t}}\
id $message_exim_id\
${if def:received_for {\n\tfor $received_for}}

In mail come via smtp all fine:
Received: from 67-41-138-21.hlrn.qwest.net ([67.41.138.21])
        by mail.domain.ru with smtp  
        (envelope-from <ejcguy@???>)
        id 1FN0Ht-0000cw-Ou
        for h-k@???; Sat, 25 Mar 2006 07:22:20 +0300

but in mail sent via shell:
Received: from " root" by mail.domain.ru with local  
        (envelope-from <root@???>)
        id 1FMxNI-0006NS-8T
        for root@???; Sat, 25 Mar 2006 04:15:28 +0300

Quotation with whitespace bug or feature exim?
