Hi,
For my part, I use this:
received_header_text = "Received: \
${if def:sender_fullhost {from ${sender_fullhost}\n\t}\
{${if def:sender_ident {from ${sender_ident} }}\
${if def:sender_helo_name
{(helo=${sender_helo_name})\n\t}}}}\
${if def:sender_ident {(helo=${sender_ident})\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 remove versions and some more or les private info but adds some more
info about crypto algorithms.
