Reversed IP check

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 joe@imcd.nl, but the check returns imcd.uk. Is there a way to avoid this?

I understand what you mean, but I'm not sure if it would help. When I do a reversed Ip Check, It will return a different domain each time. So even if I would config one FQDN for outgoing mail, it would not help. And all my domains have to point to the same IP, otherwise the incoming mail would not arrive.

Thanks for both explanations. First tip gave me a lot of info, second was part of the solution. We checked the PTR records, and found we needed to reduce the to 1 PTR record in stead of 1 for every domain. We will test that soon (as we have to adjust all MX records for the other domains's) and if it is working, we will do so for all domain's
