ok thanks
but we cant set it in the server panel
I am using gammadyne mailer and will try it out directly to see what happens.
I would have prefer to have gammadyne mailer send all quickly to emailarchitect server
and let emailarchitect server manage the sending of 15 000 emails
as well as manage throttling and number of connecitons.
i think i found how to set the number of connecitons in "Services Management - SMTP Service "
do you think that the delivery errors are all catched through the events ?
