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]>

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.
