Hi,
Is there a way, or can a way be added, to add an "auth_failed_delay=10s" style option that would put in an artificial delay after a failed password attempt?
As it stands now, Dovecot seems highly vulnerable to widescale brute-force password dictionary scans.
But not if you secure access to Dovecot using e.g. fail2ban. Why is adding complexity to Dovecot better than using a dedicated tool?
I fell in the 'use another tool' (fail2ban or similar) camp the last time, but this thread made me wonder:
Does fail2ban allow you to tarpit, rather than outright-ban, IP's? I've always thought tarpitting the better option of the two. Seems sneakier (Fight back without the attacker necessarily knowing you're fighting).
Best, Ben
