It's not the ^From: line. For example, when I send e-mail to [EMAIL PROTECTED], I think the SMTP transaction goes something like this: $ telnet localhost 25 HELO localhost MAIL FROM:[EMAIL PROTECTED] RCPT TO:[EMAIL PROTECTED] DATA From: Philip Mak <[EMAIL PROTECTED]> To: Mutt Users' List <[EMAIL PROTECTED]> Subject: Re: Where's the MAIL FROM line? Message text goes here. . The "MAIL FROM" line is not necessarily the same as the ^From: line. In mbox format, the former shows up as "From <user>[@<domain>] <date>" on the first line of the message, but Maildir format doesn't have that.
