Using One Key for a hole domain

We have a business partner who uses one public GPG key for his whole domain.

Only the email is stored in the key, but the key should be used for all mail addresses with this domain.

Earlier we used Symantec PGP, here you could set that all mails with * are encrypted with a certain public key.

I did not find this feature in kleaopatra. Is it possible to set up GPG4Win like this?

well that is not a very good setup at your partners :wink:

How to resolve it depends a bit on the Mail client you are using.

With GpgOL you could create a shared Outlook address book with all your contacts from “” and then add the “” key for each of the contacts by using the “OpenPGP Key” button when editing a contact.
