Dovecot needs one inotify entity per IDLE, maybe more for internal
purposes. So in theory, you will need: <max number of simultaneous
users> * <number of watched mailboxes per users> + <fixed amount>,
because you use one _system_ user for all IMAP-users.
Thanks. I actually had this increased previously - but for whatever
reason my sysctl.d/60-inotify.conf didn't get applied last reboot.
I'm also fighting a netfilter issue - my connection tracking counters
keep climbing. Don't know if this is in any way related.
Do you use NAT on the same machine? Or some intrusion detection
system? When you get many short connections, esp. UDP ones, the
connection tracker fills up easily.
Yes and Yes. Could fail2ban be hurting more than it's helping?
