Thank you very much. If I understand this correctly you can limit
number of recipients in message headers with the first. The second
one is a bit vague on what might be a good delay time. I went ahead
and put a small 50ms delay in, but I wondering if you or any one here
has had experience in what is a good or optimal delay value?
Thanks for the info,
Roger Heath
