# I use netstat to search ports, but nothing
[zimbra@mail ~]$ netstat -putna |grep tcp6 ( result in attachment )


I note every time i try restart proxy, its rewrite the file /opt/zimbra/conf/nginx/includes/nginx.conf.mail.imap and other respective. And in this files, the parameter listen, its using ipv4
{
server_name mail.XXXX.XXX.XX;
listen 192.168.253.22:143 ipv6only=off;
...

But i dont find where change this value for [::]:143, i dont know how to solve this, but i thin its a problem in ldap parameter, i dont know
