Continuing the discussion from [Imdb embeds broken on other sites](https://meta.discourse.org/t/imdb-embeds-broken-on-other-sites/35317/17):

I just received two mails with practically the same content (that’s weird) due to a response linked above and noticed:

My mail application KMail doesn’t strip off the signature when I reply. The issue seems to be the separator.

KMail claims that RFC compliant is `-- ` (dash dash space on a single line).

I think I found the source: [https://www.ietf.org/rfc/rfc3676.txt](https://www.ietf.org/rfc/rfc3676.txt) (4.3)

However, Discourse uses “—” (triple dash without space) as a separator.
