I am specifically interested in the Listserv functionality of the
IMail software. I currently have a listserv running on SmarterMail
and it is ok but we need something more
sophisticated/robust. Having been a long time user of WhatsUp and
very happy with it, it seems natural to look at IMail.
Our listserv is around 800 subscribers and I would expect to see
1000 or more in the next year. I doubt we would ever go over 1500
at any future date. Out current problem is speed. It takes forever
to process messages (maybe 30 minutes or so). We need for it to be
just a couple of minutes so actual discussion can take place. There
would also be a couple of other lists hosted with less than 100
subscribers. (Note the hardware and pipe is not an issue.)
I tried to help an IMGate client with his Imail list delivery, but
many years ago.
Dumping his Imail list output onto IMGate for delivery (DNS lookups,
delivery attempts, re-queue/re-attempt of deferrals, excellent
logging, and readable non-delivery msgs, etc), he got up to about 25K
msgs/hour.
Deliver depends on msg size nearly linearly. Also there is a huge
difference, per hop and end-to-end, in
a) sending a single msg to 10K recipients (fast) vs
b) sending 10K customized msgs to 10K recipients (up to 10 times slower).
The problem was that Imail would be ripping along, and thne just
stall, send nothing, with nothing shown in the Imail log. No amt of
kicking the Imail queue would change it. Then the msgs would
dribble out over 10+ hours. This was 2001 or earlier.
IMGate helps ((Imail or any mailbox server) as much on heavy outbound
of legit mail, lists or not, as it helps blocking at least 90% of the
inbound illegit crap.
