Well, as I understand it, when sender or receiver are not online, there is simply no message passing. If your concern is about what happens to the backlog when the consumer comes back online, then I've already written about that earlier today :-) > It may be time to revisit our assumptions, of course - our hosting is > dramatically better than it was when I joined the project, and even > since I started doing DSA work. > > Thanks for looking into it - something like this would be very useful > for us.

I don't know where you have read this implication, but no that is certainly not what I meant. PS: Removing the extra MLs from the Cc list.

I'm not convinced yet that this is going to work out as a debian.org service. But, that being said, I think we need something like this, and no one else appears to be working on it at the moment. Go on and make it easily installable and make people interested in it. If there are architectural problems we can't live with for our needs, we'll still benefit from your work. Thanks for doing this.
