Hi Barry,

I have no idea.

Actually, Zimbra provides a keystore for smime certs validation. But 
it's empty from any trusty external CA.

[zimbra at test-zimbra ~]$ zmlocalconfig | grep -E 'keystore|smime'
imapd_keystore = /opt/zimbra/conf/imapd.keystore
imapd_keystore_password = *
mailboxd_keystore = /opt/zimbra/mailboxd/etc/keystore
mailboxd_keystore_base = ${zimbra_home}/conf/keystore.base
mailboxd_keystore_base_password = *
mailboxd_keystore_password = *
smime_truststore = ${mailboxd_truststore}
smime_truststore_password = *

[zimbra at test-zimbra ~]$ keytool -list -keystore 
/opt/zimbra/common/lib/jvm/java/jre/lib/security/cacerts -storepass changeit

Keystore type: JKS
Keystore provider: SUN

Your keystore contains 183 entries

etc.

But no Comodo, Verisign, etc...

I added all the certs from 
https://support.comodo.com/index.php?/Knowledgebase/List/Index/71 to the 
keystore. But verification still fails when uploading personal certs.

Prabhat Kumar on comment 3 of bugzilla report says "Need to add 
intermediate as well of the s/mime certificate."
Which I did, but still no success.

It seems to me that I should first build a cert by concatenating some 
root and intermediate certs. But which certs in what order I have no 
idea :-/

Regards,
Frédéric.
