Troubles with Dovecot 2.3.3 - mkdir permission denied due to +w perm: /var, dir owned by 0:0 mode=0755)

Hi, I am quite new to Dovecot and I followed a tutorial on Linode to set up Dovecot, Postfix and MySql on the following site:- https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mys...

Everything seems to work fine(telnet etc) except dovecot does not create mailboxes. Highly appreciate if someone could check the error messages and the dovecot -n on the bottom and provide some advise. I was unable to get the SQL config but I don't think its related to SQL but more of permission related. Please help

Thanks Kevin
