From: Istvan Gabor <suseuser04@freemail.hu> Date: Sun, 11 Feb 2024 23:20:55 +0000 (GMT) Hello:This is a message where I try disabling text formatting.Before this line a left one empy line.Before this line a inserted two empty lines.These are two lines without emtpy lines between them.This is the second line.End I see this all in one line, since my client is showing me the text/plain version. (I have quoted it exactly in my reply, but your client may decide to wrap or otherwise pretty it up.) Your client is producing a MIME "multipart/alternative" body, with one text/plain version and one text/html version, and only the text/html version is formatted as you describe. Since my client lets me see the original message, complete with headers and MIME markup, I can tell you definitively that your client does a lousy job of rendering HTML to plain text. -- Bob Rogers http://www.rgrjr.com/
