New Cyrus server on Alpha

[jean-marc delpech]

Hi all,   I have been installed the last cyrus rpm on my PC and it work well so I would like now to install it on a AS 1000A. I have installed the RH 7.0 (kernel-2.2.17) and the 2 rpm cyrus-sasl-1.5.24-6.alpha.rpm and cyrus-imapd-2.0.6.3.alpha.rpm imtest OK, so I create a new user OK, then I send a mail OK. I can read the mail but after reading it I can't do anythings. If I make ls -la in the user directory all the files are cyrus:mail then when I read the mail the mail, the cyrus.header and cyrus.index are cyrus:root. Many thks if you can help me :)   Jean-Marc
