title: Send emails via SMTP - Test spam filters
body: <p>I am planning to implement a service to test the capabilities in spam detection of modern Email clients, as well as webmail services like gmail, hotmail...</p>
  
  <p>The project is in a very early state and I am actually just figuering out which techniques may be the best, or finding a way to do that.</p>
  
  <p>My actual plan is: setting up a local mail server which receives a bundle of spam mails. It forwards the mails with original headers (so the receiver thinks the mail was sent directly) to my accounts on various platforms. The Im planning to download the mails which were not detected to calculate the result of detection.</p>
  
  <p>The problem might be, that my IP (of the sending smtp server) will be on most blacklists after a short time. Does anybody have suggestions to circumvent this problem?</p>
  
  <p>Please do not discuss how I will get the Spams, or how i will extract the results. This thread should only be about sending emails.</p>
  
  <p>Please do not judge me as spammer, of course there will be no abuse of the system. This is for research purposes only!</p>
  
  <p>Thanks for suggestions!</p>
