dovecot - Jan 2005 - Is it possible to access maildir w/ 2 clients at the same time?

Hi,

I have dovecot with Maildir installed and running. No problems.
I use kmail on both desktop and laptop with cachedimap configuration. 
kmail is configured to look for new mail every two minutes.

Now my question:
When both maschines are running and kmail is started then two clients access the
same Maildir
on the server at the same time. Is this possible or can this corrupt the Maildir
directory.

TIA
Guenther

The whole point (or at least a major part of it) is that maildirs are
designed to be concurrently accessed (provided that the clients Do It
Right). See for example http://cr.yp.to/proto/maildir.html,
http://www.qmail.org/qmail-manual-html/man5/maildir.html or just google
for maildir.

Cheers,
Magnus

nope it wouldnt corrupt your maildir
but they can mask new mails. if client1 sets the read flag before
client2 saw themail. thats it.
