Dear Keith:
I think you got my point, thanks.
My experience on sendmail at this tpoic *is* quite good - sorry, I don't
have such experience on qmail yet.
My intuition tells me that the first way will be better, since it will send
only one copy of messages on network. If I have a 30KB+ message size, and
400K subscribers, the first method 'seems' to be much more efficient than
the second one.
However, this is what I 'think' - no real world experience on qmail yet.
I'll examine this behavior on qmail soon, the machine is still in the box,
I don't have time to open/assamble/install it these days.
Our newsletters have 'sponsors', and some information is time-intensive,
so my life is harder and harder.... :(
Anyway, thanks for any comment on this tpoic.
