You shouln't rewrite or remove received headers, they are useful for loop
detection and things like that. However, you can define what is going to these
headers. But you can use this:
received_header_text = "Received: \
${if def:sender_fullhost {from ${sender_fullhost}\n\t}\
${if def:sender_helo_name {(helo=${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:tls_peerdn {(tls_peerdn ${tls_peerdn})\n\t}}\
id=${message_id}\
${if def:received_for {\n\tfor $received_for}}"
It does a great log in case of problems, but does not reveal too much internal
data.
