SPX with Exchange 2010 for internal encryption

Hi,

we use the email appliance for several years now and haven't used the SPX before as we used PGP. Now we want to provide mail encryption for all with Sophos SPX. We want to be able to also encrypt mails from internal to internal. (mailbox to mailbox)

As we have a gateway solution implemented yet, we now have the problem to get the internal traffic also over one SPX appliance. How can this achieved?

I have no possibility to configure the send connector to route all mails with header "confidential" to the internal SPX-appliance. And if I route all traffic over the appliance, how do I avoid bounces?

Is there a white paper with a szenario for internal encryption and not only gateway encryption?

Any hint is welcome ;)

Thanks in advance

Torsten

  • Hi Antonius,

    unfortunately this is no option for me. As you mentioned I would have to switch from RPC to SMTP and what would I do with the external clients which are connected via RPC over https?

    I thought about a SMTP-connector for the Exchange. Something that routes the "confidential" traffic over a connector to the SPX and the SPX back to the Exchanges. I don't know but it seems that the SPX is only for external communications. We do have some internal communications which have to be encrypted.

    Maybe this is a feature request to get the SPX also for internal use working.

    I have already tried to implement one SPX between the CAS-Server and the TransportServer and build up something like a connector to route all traffic through the SPX, but I am afraid of bouncing mails.

    Thanks and regards
