If "From" (no quotes) begins a line in body text, it is prepended with reply prefix (e.g., >)

[judenile]

If you begin a new line with the word "From" (no quotes) followed by a space, then followed by any word or character string, the line that begins with "From" (no quotes) will be prepended with the reply prefix of ">" (no quotes).

This anamoly will only be seen by the recipient (or cc or bcc). So to test, you must send the email somewhere (including to yourself) and then view it as a recipient.

Example:

If, in Mulberry, I compose and send the following text:

This is a test.

From time to time...

to any email address, and view that message in an email client or a web-browser client (e.g., gmail), the text will be displayed as...

This is a test.

>From time to time...

Depending on the email client and the formatting type (plain, rich text, HTML) set in the client's preferences, the reply prefix will vary (>, |, etc) -- but it will always be present in some form.

Within my OS (OS X 10.4.9) I have tested with Mulberry, Mail (v. 2.1), Eudora (v 6.2.4), and browser-based gmail (using both Safari and Firefox.) All 100 percent reproduceable.

This is a server issue at the recipient. Servers which store mail in mbox format must add the ">" prefix as a line starting with "From " is used to identity the boundary between two emails. Try sending to a recipient who's server uses maildir or other storage format.
