hi, First of all: how did you install cyrus? did you download it from somewhere???? a) cyrus is shipped with your cd's on fedora core 2 (cd 3 & 4) b) as Alexander said, better use yum for the installation, cyrus has lots of dependencies and needs 4 rpms: - perl-Cyrus - cyrus-imapd - cyrus-sasl (should already been installed) - cyrus-imapd-utils - cyrus-imapd-nntp - cyrus-imapd-murder - cyrus-imapd-devel installing it via yum also creates a user called cyrus, which you have to use tocreate your databases. after your installation do: - start cyrus-sals : /sbin/service/saslauthd start - start cyrus-imapd: /sbin/service/cyrus-imapd start to create the user-mailboxes, su to cyrus (do not forget to give him a password before....) and start the admin-program: cyradm localhost you will have to indicate your password for your cyrus-user again, otherwise you will fail to get into the admin-interface. now you can manage your mailboxes. By default, cyrus & saslauthd authenticates against users in your /etc/passwd /etc/shadow -files. So, you will have to create the appropriate users for your mailboxes. If you like to use mysql tell us. BEFORE YOU INSTALL MAKE SURE YOU REMOVED YOUR OLD CYRUS-INSTALLATION PROPERLY, DO NOT FORGET TO MV IMAPD.CONF AND CYRUS.CONF TO OTHER FILENAMES. let us know, if this helps. Roger
