dovecot - May 2006 - maildir format

Hello Timo and other dovecot-dev or users,

   It looks like Dovecot accepts (with APPEND command) messages that  
begins
with 'From[SPACE]' line, which are not valid from RFC 2822 point of  
view.
Additionnally, Dovecot will store them as they are APPENDed, I mean
with the starting 'From[SPACE]' line, which generates a bad Maildir  
format.

http://www.qmail.org/man/man5/maildir.html states the following :

<<
           Each file in new is a newly delivered mail message.  The
           modification time of the file is the delivery date of the
           message.  The message is delivered without an extra UUCP-
           style From_ line, without any >From quoting, and without an
           extra blank line at the end.  The message is normally in RFC
           822 format, starting with a Return-Path line and a
           Delivered-To line, but it could contain arbitrary binary
           data.  It might not even end with a newline.

The alternative would be to fail the operation completely. I don't see
that as very good idea.

Here the "could contain arbitrary binary data" looks to me like there
aren't really any restrictions as to what the message could contain,
including a From-line at the beginning :).
