The big gain in using ezmlm here is that you have a pretty much "clean"
userbase. Users that don't have valid email addresses cannot subscribe
because they don't get the confirmation request back. So the only
dropouts are addresses that got deleted which in turn will be
automagically unsubscribed by ezmlm.
I had posted the URL of a picture that shows the delivery of the 95000+
newletter in the past, here it is again:
http://www.lamer.de/maex/creative/software/qmail/deliver-stats2.gif
The delivery starts at about timestamp 300 and the first pass is
finished at around 2950 (scale is seconds).
The next two peaks are retries.
a high percentage of the subscriber base is at yahoo addresses :((
The problem ist that the mail servers are very unresponsive and at
certain times quite a lot of delivery slots are filled up with hanging
delivery attempts which degrades the performance :((
But as this is a dedicated server for that newsletter at the moment
there is no need for optimising at the moment (could be done e.g. with
a second qmail on that same machine that gets all the yahoo mails, so
they're out of the way for list delivery).
