如何向asp.net中的dropfolder发送电子邮件？

Question

I have two questions: 1) How do I send an email in C#, but have it end up in a drop folder to be sent from there rather than being sent straight out by SMTP?

2) For a production machine, do I use IIS to process the dropfolder, or should I purchase a 3rd party product for this?

Thanks!

Answer 1

In your web.config:

<system.net>
  <mailSettings>
     <smtp deliveryMethod="SpecifiedPickupDirectory">
      <specifiedPickupDirectory pickupDirectoryLocation="C:\myDropFolder" />
     </smtp>
  </mailSettings>
</system.net>

Whether to use IIS or some third party product... I guess that depends on your needs. Is there a particular feature you would like and that the IIS SMTP server does not have?

Answer 2

You can also set this in code on the DeliveryMethod property of the SmtpClient object.

SmtpClient client = new SmtpClient();
client.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory;
client.PickupDirectoryLocation = "C:\DropFolder";
