Are there any consequences to stripping out the Received header that contains the sender’s IP address (and usually their LAN address as well)?
And is adding to header_checks.pcre: /^Received: .*ESMTPSA.*/ IGNORE Enough to strip it out, or does it need to be in mime_header_checks as well? (I’ve found conflicting information on this in google searching.) -- 'I thought dwarfs didn't believe in devils and demons and stuff like that.' 'That's true, but... we're not sure if they know.'
