I am looking for a method of effectivly sending hundreds of emails from my asp.net web app.
There are 2 problems in my current solution (not using SmtpDeliveryMethod.PickupDirectoryFromIis):
1. Sending lots of emails hangs up the app for a long time (while sending is prosessing, one email at a time )
2. I do not know any method of programatically controlling what emails do not arrive at the recipient (this is important in some instances)
I have read about something called SmtpDeliveryMethod.PickupDirectoryFromIis.
As I understand this is a way of spooling emails in a rapid way to some file on the web-server, letting IIS take care of the sending later on. But articles I read seems to tell me just half the story...
Can anybody give me an explanation of what I have to do in my app and what my hosting comapny must do at their server?
