Hi.
Earlier today I was hit with 612 login attempts in 7 minutes. They
ramped up slowly, too. :-)
They quickly hit the file descriptor limit. And then a login server
spawned and died so quickly that dovecot just died.
My question is, is there a way to throttle the number of login
connections? I'm doing it in my firewall now, but it would be nice
to be able to say something like "max-login-attempts: X" before we
blacklist the IP (for some configurable time).
yeah, I know V4.2 :-)
By the way, I *really* appreciate all the effort that's gone into
Dovecot. Great work, everyone.
Sean
