it doesn' t make a difference, whether I choose INLINE or MIME.

Could it be that the message is PGP/INLINE encrypted (as opposed to
PGP/MIME) and you did not select "Incoming PGP/INLINE enabled"?

You mean choose from the sending application? If the incoming email is
PGP/INLINE encrypted, you need to enable "Incoming PGP/INLINE enabled"
otherwise the gateway will not scan the message for PGP inline parts.
Can you send me (off list) the message that was not decrypted?

Kind regards,

Our problem is, that we have created the internal account guenther(a)in-put.de

in the ciphermail webinterface and the corresponding imap account guenther.

Then we uploaded the private gpg key and told ciphermail that it is a trusted

key.

When we now send an gpg encrypted email, the MPA log contains the following

Hm, ciphermail doesn't even try to decrypt it, but sends it to the local IMAP

server.

Probably it is just a single option that is missing, but which is it?

Could it be that the message is PGP/INLINE encrypted (as opposed to
PGP/MIME) and you did not select "Incoming PGP/INLINE enabled"?

it doesn' t make a difference, whether I choose INLINE or MIME.
