We are testing EDI messaging with a government department however it seems that Thunderbird keeps stripping the attachment before the email reaches the exchange and produces this error.

We sent 3 messages:

1. 2 had this error: PKCS#7 argument error: malformed S/MIME encoded PKCS#7 object 2. 1 had this error: no attachment on their end

PKI Certificate is installed in Thunderbird.
