Hello,
We use PGP based email encryption using the gateway and the customer
uses tobit david as their mail server with S/MIME. Our public key is
installed on their mail system.
When they reply to one of our emails we get it S/MIME encrypted, with
their certificate attached. Email that aren't a reply to one of ours
work fine.
Not sure whether I fully understand the problem.
So if you send a message signed with PGP/MIME and the recipient replies,
the reply is S/MIME encrypted with a certificate for which you do not
have the private key? But if they send you a message which is not a
reply, the message is not encrypted?
Kind regards,

Is there anything we can do on our side to fix this?
