A (blacklisted) dynamic IP-address in a Received header line is normal.
Most honest users worldwide are in this situation.
IP-address of your server is searched in blacklists,
not IP-addresses from every Received line in the header.
Please give an example of full unredacted header and the
error message your user got while trying to send that message.
Also, check your server in
