How can I send smtp message in rapid succession to benchmark my smtp parser?

i have a smtp listener that i used this free tool to unit test because i am not so hot with command line and telnet.

is there a tool (multi-threaded maybe) i can use to send loads of smtp messages to test and benchmark my listener app?

Have you looked into the System.Net.Mail.SmtpClient class?

kaufmed: i thought that without an SMTP server it would not send mail.

since i dont have an SMTP server, i want something to crank out smtp messages to my server running my listener over port 8000.

The SMTP class will send its data using the SMTP protocol to whatever server and port you tell it to. For example, have a look at this question where I wrote a crude SMTP listener and then used the SMTP class to send mail to it:
U.S. Department of Agriculture and Acronis Access

With the new era of mobile computing, smartphones and tablets, wireless communications and cloud services, the USDA sought to take advantage of a mobilized workforce and the blurring lines between personal and corporate computing resources.

kaufmed: than ks that was my question and the sample is working very well. I found that if i send a bad message the listener just dies and subsequent sends dont have the port open anymore.

the sample is great in taking a single message but i need it to run 24/7 and take multiple messages. i have been pointed to multi-threading this now. what do you think about that?

LOL. I didn't realize you were the same person! Sorry about that.

My MT-fu is not that strong, so I'm hesitant to provide you with an example. I'll think about it, though, and see if I can work it out  = )

i couldn't find an app for this so i made a multi threaded app to spam the listener. i made the listener multi threaded using an threadpool and it is able to eat 20,000 mails being sent from 2 locations concurrently. now to devise a way to get that info to a SQL table without creating a huge bottle neck.
