We have several Mailservers in different countries, all have their own domain, imcd.nl, imcd.be, imcd.uk etc. In one location we have an Email Appliance, for incoming and outgoing mail. That's why the A-records of all these domains point to the same external IPaddress. It happens many times, we send mail to companies, who do a reversed IP check, and then it can happen we send from email@example.com, but the check returns imcd.uk. Is there a way to avoid this?
