I have problem with signing multipart mail. If I try send simple signed mail it is delivered and Thunderbird says its signed and correct. But if I send multipart mail it is delivered but Thunderbird says the mail was signed but the signature doesn't match the content. Where's problem? Is it possible to sign multipart mail?
