milter and Ciphermail is a content filter. Milters are applied before

to figure this out as I was not aware of the described processing order.
Finally I found this out just by reading the (previously ignored)
headlines of http://www.postfix.org/FILTER_README.html
Adding the DKIM milter on the reinjection port(s) should work. After
handling the mail (i.e., encryption/decryption etc), the back-end sends
the mail back to postfix on a "reinjection port" (port 10026).
I haven't tested it but the following might work:
See the following line in master under the 127.0.0.1:10026 section:
You should change this line to something like:

Interesting .. thanks for your reply.
Then again, you suggestion of using dkimproxy is also a good alternative
until DKIM support has been added to CipherMail*.
* "native" DKIM support is basically working but not enabled for all
SMTP outgoing mail. We will see whether we can make it possible to
enable this for all outgoing email.
Is there a timeline for new releases and a list of planed features.
A nice feature would be some thing like this:
offers this feature. There are
several ways to use it. It requires that a web portal is accessible from
the Internet. On way is to tell the software to detach the attachments
of mails, store them and generate a mail for the recipient with a link
for the download. You also can generate a mail which allows the
recipient to upload a file, and write a comment. Then you get notified
by mail and you can download it with a generated link.
Just an idea for a enhancement :-)
