A signed email message with attachment is sent through Aspose 6.4 to gmail. Signature is included using AttachSignature method msg.AttachSignature(certSigning,true). When the email is viewed in Gmail Client, there is no indication that the email is signed. The signature is not included in email. A noname file is included instead.
