Maybe I should send my reply to the list as well... :-)

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.
