<p>The only thing that annoys me is that, apparently, the public key
of a received signed message should be automatically added to the
sender contact (as stated here
<a class="moz-txt-link-freetext" href="https://www.zimbra.com/email-server-software/email-encryption/">https://www.zimbra.com/email-server-software/email-encryption/</a>)
but this does not work with the latest Zimlet. This requires the
sender and recipient to first exchange their public certificate
and add them to each other's contacts to start encrypting emails.<br>
</p>
<p>Can't remember if this auto add feature ever worked with the
previous Java Zimlet. If anyone has a clue...</p>

<p>Hi folks,<br>
</p>
<p>I finally found the right certificate to add to Zimbra keystore
:
<a class="moz-txt-link-freetext"
href="http://crt.comodoca.com/COMODORSAClientAuthenticationandSecureEmailCA.crt"
moz-do-not-send="true">http://crt.comodoca.com/COMODORSAClientAuthenticationandSecureEmailCA.crt</a></p>
<p>Thanks to Stefan and his advice on using cert-chain-resolver.sh
from <a class="moz-txt-link-freetext"
href="https://github.com/zakjan/cert-chain-resolver"
moz-do-not-send="true">https://github.com/zakjan/cert-chain-resolver</a>,
I could get the right root and intermediate CA certs that Zimbra
needed (out of my personal cert file):<br>
</p>
<p>What you need to do is:<br>
</p>
<p>- export personnal certificate from firefox to create .p12 file<br>
- converted the certificate to PEM with:<br>
openssl pkcs12 -in myPersonalCert.p12 -out myPersonnalCert.pem
-nodes <br>
- use cert-chain-resolver.sh to create chain: <br>
cert-chain-resolver.sh -o comodo-root-and-intermediate.pem
my-personnal-cert.pem<br>
- comodo-root-and-intermediate.pem should contain root and
intermediate CA certificates. Keep root cert only and add it to
Zimbra:<br>
zmcertmgr addcacert /tmp/comodo-root.crt</p>
<p>No need to restart mailboxd and you can keep
zimbraSmimeOCSPEnabled to TRUE.<br>
</p>
Regards,<br>
Frédéric.<br>
