Re: [Dovecot] pop3 rate limit

Hi,

we have customers with Exchange servers that are polling for new mail every minute with dozens of pop3 accounts. I am looking for a mechanism to rate limit this per user. So what I am looking for is a way to block users from polling, if a user asks for new mail more than every 5 minutes (for example).

Is this possible? Can this be achieved within Dovecot or does it need external scripting? (I thought about fail2ban, but also want IPv6 support)

Thanks in advance

You'll need to use v2.1 to get IPV6 support.
