Greetings -
I'm looking to apply some rate limiting on incoming emails from certain
hosts on our Exim 4.86 setup. I'm familiar with using the *ratelimit* ACL
condition to measure rate and decide whether to take action.
>From the example in the Specification it looks like when the threshold is
reached I use *delay* to introduce a delay. However *delay* takes a
standard Exim time interval: an integer number of seconds, minutes, hours,
days or weeks.
Is there a way of using a *fraction* of a second for the delay — eg, 0.5
seconds — or would I have to look at using the old-style
*smtp_ratelimit_{hosts,mail,rcpt}* options instead to achieve this, with
the disadvantage that they only apply within a single connection?
With many thanks,
Mike B-)
