Hello!
We allow our users to sign their messages. We do it like this:
Smime secureMime = new Smime();
message = secureMime.Sign(message, mailbeeCertificate);
Let's say that sender of the message is test@gmail.com.
After signing message IsSigned property is set to true and ContentType equals "multipart/signed". We received that message in Thunderbird and it says that it's signed. Everything works fine. But when we delete test@gmail.com account (both in Thunderbird and our mail client), configure it again and synchronize folder "Sent", the message is unsigned. Its content type is set to "multipart/alternative". What can cause this problem? Why signed messages downloaded from "Sent" folder are not signed?

Not sure if I understood this correctly, specifically regarding the folder "Sent", where does that one come from? Did you actually upload the message there with MailBee, or it was placed by Gmail there?

Yes, after sending that message I uploaded it to folder "Sent". And that's where we are losing information that this message was signed. I will try to fix it. Thanks for your reply.

Maybe you sent one message and uploaded another?
E.g.
msgSigned = SignMessage(msgNotSigned)
Send(msgSigned)
UploadToSent(msgNotSigned)
Regards,
Alex

No, I found out that we sign the message which is then sent by SmtpClient and later in next operation we upload this message to "Sent" folder by ImapClient. I have to sign that message again before uploading and it will work fine. Thanks for your time :)
