I don't know if this is related, but we have seen situations where we have
attempted
to send a large quantity of emails simultaneously (around 50 or so) which
were queued
up in Eudora. The addresses are all valid, but some are kicked back as
invalid because
(it seems) IMail can't handle the load. In Eudora we then resend those
three or four
(which Eudora keeps queued) and they go out OK.
So perhaps what you are seeing is that you send the batch to the list and IMail
chokes on itself, unable to keep up with the volume of the list.
You could remedy this in CF by doing a CFLOOP through the list and,
say, every 20 or 25 messages, do an embedded loop for a half a second, to
give IMail the
change to catch up to the submissions.
Any thoughts?
