Hi, failed to send an email with smtp block error.
check of the logs showed the account had these errors
server dovecot: dovecot: All login processes are in use. You may need to increase login_max_processes_count
server dovecot: IMAP(firstname.lastname@example.org): Inotify instance limit for user exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances
I have done a google and seems i need to edit one or all of following settings
login_process_per_connection = yes
login_processes_count = 3
login_max_processes_count = 128
login_max_connections = 256
this what dovecot.conf do i use and what is exact sysntax?
echo 256 > /proc/sys/fs/inotify/max_user_instances
