Hi

Would be great if you could add S/MIME support.

Currently for Android there are very few apps that allow signing and encrypting of emails using X509 certificates.

There is .free fork of K-9 that can do it rumour has it.

There is also djizigo now renamed to ciphermail.

In the forum there is another topic about s/mime problems where the answer is that you are working on some kind of s/mime support.
