Some weeks ago I installed a new ispconfig3 server with posfix/dovecot, the problem was with the mail traffic, it was on "0" for all accounts, I readed on the furum that is not posible to generate the mail traffic with dovecot server, For this reason I removed dovecot and I installed Courier on my server and I did the following: 1) I downloaded ispconfig and ran the ispconfig update.php script. I Choosed yes when the updater asked me to reconfigure services. 2) The maildir structure of dovecot and courier are not compatible, I moved all files which are in the "Maildir" subfolder to the root folder of the maildir accounts. E.g.: mv /var/vmail/domain.tld/user/Maildir/* /var/vmail/domain.tld/user/ 3) I Edited the postfix main.cf and comment out the line that contains the authentication "private/auth" and I replace the "smtpd_sasl_type" from "dovecot" to "cyrus": smtpd_sasl_type = cyrus #smtpd_sasl_path = private/auth Then I restarted postfix. Evereting works, Accounts send and receive emails, not big problem and now the system is generating the mail traffic. BUT the problem start when I created a new account, the sistem create the root folder for the account normaly but the folders .Send .Draft .Trash are being generate inside of Maildir folder and the Courier do not detects this folder inside of Maildir, I have to move it to the root directory manually How can I solve this issue?
