Hi, everyone: I have a list of more than 18,000 subscribers. When I distribute a announce once a week, it takes up to 8 hours for delivery. During the 8 hours period of time, no jobs can be process at all. Any way to speed this thing up ? Also I have installed a eval LSMTP on a NT box. I am trying to see if I can point the mail delivery to the LSMTP and speed up the whole thing. I can not turn the whole listserv delivery to LSMP because of the risk of 18,000 complaints. Can I setup just one test list dilivered through LSMTP? (is "Internet-Via= " the trick ?)
