SOLVED ISPconfig 3 Ubuntu postfix+dovecot+roundcube I decided to try a multiserver setup. The mail control panel server also as function of mail server. Followed 2 tutorials: http://www.howtoforge.com/perfect-server-ubuntu-12.04-lts-apache2-bind-dovecot-ispconfig-3-p7 and http://webmodelling.com/webbits/ubuntu/ubuntu-ispconfig3-multi-server-setup.aspx Also, I have 2 STARTSSL certificates: 1 for the control panel port 8080 https://cp.mydomain.com:8080 1 for the webmail https://mail.mydomain.com (the last one was tricky since I'm not using a wildcard SSL, but successfully manage to change the roundcube.conf to respond using the correct mail SSL certificate and to respond to the domain instead of domain/webmail. For this is used the how-to http://www.howtoforge.com/securing-your-ispconfig-3-installation-with-a-free-class1-ssl-certificate-from-startssl-p2 the only difference from the above tutorial was postfix and dovecot, I changed them to reflect the mail SSL and not the ispconfig3 cp.mydomain SSL. So far so good, everything responded fine. The issue: I already created email accounts in ISPconfig3. When trying to login in roundcube https://mail.mydomain.com I'm getting login failed. Checking the /var/log/mail.err: Code: mail dovecot: lda(root): Error: user root: Initialization failed: Initializing mail storage from mail_location setting failed: stat(/root/Maildir) failed: Permission denied (euid=65534(nobody) egid=65534(nogroup) missing +x perm: /root, dir owned by 0:0 mode=0700) checking mail.log: 3 warning lines with the 3 dovecot SSL entries, althought it's a warning it creates a lot of logging Code: mail dovecot: config: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:92: ssl_cert_file has been replaced by ssl_cert = <file and Code: mail dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<firstname.lastname@example.org>, method=PLAIN, rip=192.168.1.10, lip=192.168.1.10, TLS Help would be appreciated.
