Issues when posting via e-mail

I've encountered the following issues when posting to soup via e-mail (the first issue may well be an "undocumented feature":
1 Paragraph breaks are stripped out of the text. This appears to occur irrespective of whether a Plain Text or HTML message is used.
2 On one occasion so far, the text appeared twice within the same post. (Unfortunately I've already edited to remove the duplication and restore the paragraph breaks):
Why soup.io? - Maskil's soup

Update:
Further to my original comment, it appears that the duplicated content within a single post occurs when posting by means of an HTML e-mail message. I will test later to confirm whether it occurs with Plain Text messages or not, but I don't believe so. Please see the following recent posts as examples:
