如何在debian 6上运行exim4的邮件头中删除本地用户名？
Received: from root by host.domain.com with local (Exim 4.72) (envelope-from <[email protected]>) id 123123123 for [email protected]; Tue, 03 Jan 2012 13:08:17 +0100 所以我想一起删除根和本地主机名（？）的部分。
您需要根据文档修改received_header_text 。
它默认为：
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}}\ (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}}
修改后它将是：
received_header_text = Received: \ 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}} (IT IS WORKING CODE)
