Encrypted Mail - Domino --> Domino, Exchange, others

Hi all,

Please could somebody give me a few pointers for encryted messaging products or solutions that encompass -

Domino to Domino

Domino to Exchange

  • Domino to any other mailers

I have checked RSA site, Verisign site, starting to look into S/MIME now but its a minefield of exceptions. They appear to provide a digital signer, but struggle to explain solid encryption.

I was hoping for a solution that only depended on 1 cert eg in org certifier for each company, rather than a cert for every person. So all messages sent/received from a domain is encrypted. But do not want a message to goto a hijacked domain, that has obtained a Verisign cert for example and is able to decrypt the message because they are simply under the verisign org umbrella. It must be specific point to point like cross-certifying Notes Ids

Domino to Domino we cross-cert and use -

NRPC over VPN if they have CheckPoint FW-1

X.PC over Modem - (we use port encrytion option)

Telex or Fax if not above

Domino to Exchange

SMTP over VPN if they have CheckPoint FW-1

Telex or Fax

Domino to Others

SMTP over VPN if they have CheckPoint FW-1

Telex or Fax

As you see, many times we need to fall back on Telex and Fax, which isn’t the easiest of systems to maintain robust applications integrated with Notes.

Any ideas would be appreciated.

Regards

Paul
