When the content transfer encoding is 8bit, all the mail that are signed is getting failed. Have attached the eml of the failed mail. Please provide the fix for this isssue. dkim_8bit.txt

I'm facing the same issue. Is there any update?

krish93 commented 6 years ago

Convert the 8bit encoded mail to quoted-printable before signing It will solve the issue you are facing. Refer this url https://tools.ietf.org/html/rfc4871#section-5.3

Thanks, mine issue was that for some reason "mail.smtp.allow8bitmime" was set to true causing JavaMail to automatically convert messages back to 8bit
