OpenSSL smime verification fail about nodemailer-smime HOT 3 OPEN

I second this. Thunderbird seems to flag the signature as non-valid. Would be nice to get any info about how to solve/debug this.

from nodemailer-smime.

I can reproduce this; https://gist.github.com/tg44/897b69e8539183b20d2ec6b316fcd25b

• The first is the original test, with some little modifications.
• The second is a not working sign
• The third is working again

Test code; openssl smime -verify -in out3.email -noverify

In summary; if your email is not multipart, the sign will fail. If your mail is multipart, the sign will be ok! We have html emails, so with the nodemailer-html-to-text plugin it will probably work without any effort...

For anyone finding this and having issues with signing: to make your email multipart, you'll need both html and text properties on your sendMail call.
