Buon giorno

Thanks for your confirmation and your suggestion concerning the working domains.

I let have changed the DNS entry as I described and now also the "mailing partner" is satisfied with the HELO.

yes this is the right solution, it is easyer and make definitelly sense.... at least for me :)

Also, the suggestion I use to give is to use a main domain name that is not going to host any account but postmaster, and use "working domains" as additional ones. This allow much more flexibility in operation.

Actually there is no problem at all to use directly the MDN as working domain, so no reason to change the setup, but generally speaking for new set up this is the long term solution with less problem... think about you company or institution define to change the domain name ....

Thanks for explanations 

Instead to change the FQDN for the mail server to, could it be the easiest solution to change the DNS entry for to than instead?

Also the MX entry should be instead of ?

Reason: the forward lookup for points already to the correct IP, so there is no need that the reverese lookup is Also when sending a mail from outside to the lookup of MX of has the correct IP as result. There is no need to use

Thanks for further help
