Mail Encryption when the recipient has a privately signed CA

rtos

Hello,

we use Sophos Mail encryption with official certificates for our users everything works fine but only when the recipient (at another company for example) also has official S/MIME certificates.

If the Sophos does not trust the Authorities it will not import the S/MIME Certificate which makes sense for me but what i don´t understand is that it will Download the untrusted CA and save it under "Local S/MIME Authorities" but then still not import the S/MIME Certificate.

 

I think the sophos Downloads The CA  if the certificate has a link embedded to to it  like this.

    Hi, i just checked again.

    It will only import the CA´s if th CRL is Configured in the S/MIME Sginature.

    What i don´t know does the Sopos automatically trust the CA it gets it from those CRL information's ?

    For me it looks like it does from the Web interface, as it lists them under Local S/MIME Authorities and Enables Them by default.

    .

    But then it wont Import the Corresponding S/MIME Certificates as if the Authorities are not trusted.
