You could put a 'slightly less' informative received header by setting
this in the beginning of your config file:
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}}"
