we have created a pair of keys Thunderbird/Enigmail.
The private key has been imported into the Ciphermail gateway on the client side, the public key into our Cipermail gateway.
When sending an email to the address the keys have been created for, our gateways sends a notification about a successful encryption.
But the gateway on the other side isn't able to decrypt the message:

To test our configuration we created another pair of keys, this time on the Ciphermail gateway of the client, with identical settings for the user, except for the email address. With this account it is possible to decrypt an email.
Therefore we assume, that there is a problem with the handling of the imported private key.
"WARN PGP decryption key not found; Recipient Key IDs: [442345413151FE6D];"
so a PGP key with private key with key id of 442345413151FE6D cannot be
found on the receiving gateway. The picture from your email named
"details_private_key.png" shows that there is no private key:
"Private key Available: false"
I'm note sure whether the image "details_private_key.png" is a
screenshot of the receiving server but if so it seems the private key
was not imported only the public key. Now it could be that there was
some error on import but it might also be that only the public key ring
was exported from Thunderbird and not the private key ring.
Kind regards,
