Email not being recognized as PGP encrypted

Gateway

Hi,

we have setup a PGP encryption between one of our customers (using ciphermail) and his tax accountant (using enigmail).

The tax accountant has to send loan reports only as an encrypted email.
We exported the public pgp key of the customer and imported it successfully into enigmail. Did the same with my public key.
The public key of the customer has been in use in our ciphermail installation for at least 4 months.

When the tax accountant sends an email to my address it is encrypted and decrypted.
When the tax account sends an email to the customer it is encrypted but not decrypted:

I have access to the customers emails and I see the encrypted email.

When I send an encrypted email to the customer, the log contains the line

25 Nov 2015 13:21:09 | INFO Message has been PGP decrypted; MailID: 9a6a2080-8a10-4aff-9370-3fab14845438; Recipients: [xxxx(a)xxxxx.com] (mitm.application.djigzo.james.mailets.PGPHandler) [Spool Thread #1]

There is one difference between the two ciphermail installations: Our customer has a user profile for the tax accountant, we do not. I therefore assume, that I made a mistake in the configuration of that profile. But which parameter could prevent an email from beeing decrytped? Why does one ciphermail installation recognize the encryption and the other one not?

Thanks for your help,

Stefan

we have setup a PGP encryption between one of our customers (using

The tax accountant has to send loan reports only as an encrypted
email. We exported the public pgp key of the customer and imported it
successfully into enigmail. Did the same with my public key. The
public key of the customer has been in use in our ciphermail
installation for at least 4 months.

When the tax accountant sends an email to my address it is encrypted
and decrypted. When the tax account sends an email to the customer
it is encrypted but not decrypted:

[SNIP]

I have access to the customers emails and I see the encrypted email.

When I send an encrypted email to the customer, the log contains the
line

25 Nov 2015 13:21:09 | INFO Message has been PGP decrypted; MailID:

Most likely, the email sent by the tax accountant is encrypted with
PGP/INLINE but PGP/INLINE is not enabled for the recipient (either
globally or on domain or for the individual recipient(s)).

Can you check the following:

1. Is the email that was not decrypted, encrypted with PGP/INLINE?

2. Is "Enable PGP/INLINE to internal" checked?

Kind regards,
