dovecot - Oct 2004 - migration to maildir and arrival time

Hello.

I am currently testing dovecot (0.99.10.8, Debian woody from backports), 
with the maildir storage.

I have noticed that when I use the mailutil tool from uw-imap 
distribution to transfer my IMAP mailboxes from our current server 
(uw-imap, mbx format) to the dovecot one, the mails arrival time are 
apparently lost. I can see this in Pine, using the Arrival sort: the 
mailboxes on the originating server and dovecot server are not ordered 
the same. If I use the mb2md perl script to transfer the same mailbox, I 
see the same behaviour.

Is this normal ?

Thanks.

Dovecot gets the arrival time from maildir file's modification 
timestamp. If your scripts don't set that correctly, that's the 
problem.

My script just uses the mailutil tool, which sets the arrival correctly 
AFAIK. When manually using pine to copy from the source server to the 
dovecot+maildir server, I see the same behaviour: the resulting mailbox 
looks like reversed (last messages received displayed first in pine).

For example, I use this:

mailutil copy -verbose '{source-server/user=kowalski}toto' \
 		       '{dovecot-server/user=kowalski}toto'

When the destination storage format is maildir, the mailboxes are not 
the same. I checked the contents of the maildir, in the .toto/cur/ 
directory. What I see is the files having correct mtime (I also checked 
their contents). But when I use pine, and its arrival sort, to look into 
this 'toto' folder, the last message received is as the top.

When the destination storage format is mbox, there is no problem, the 
mailboxes are the same.
