Notice:
If you want to support more than 128 simultanously connections (the default),
you have to increase \"/proc/sys/fs/inotify/max_user_instances\".
\033[33m\033[1mNotice:\033[m
The Dovecot Service is configured to support more than 128 simultanously connections.
If you are running dovecot on a VServer Guest System, you have to do that on the
VServer Root System:
So, you have to \033[1mincrease /proc/sys/fs/inotify/max_user_instances\033[m (default is 128):
# echo \"fs.inotify.max_user_instances = 1024\" >> /etc/sysctl.conf
# echo \"fs.inotify.max_user_instances = 2048\" >> /etc/sysctl.conf
# sysctl -p
If you are running dovecot on a Virtual Guest System, you have to do that on the
Host (Root) System.
