Hi, I am not a user of qpsmtpd, but one of customers is (they use smeserver which I think I am right in saying using qpsmtpd). They are a PR company and so every now and then need to send out mailshots to journalists etc. When they do so qpsmtpd starts a very large number of parallel sessions rather than doing them one (or some small number) at a time. This cripples their network and while the traffic is being dispatched they have to stop using the web as performance is just dire.
So my question is whether there is a way to configure qpsmtpd to limit the number of concurrent outbound sessions. David
