title: Sending an e-mail in java without the JavaMail API
body: <p>I'm developing an application, where users have the option to have sent an e-mail to a specified e-mail every x minutes.</p>
  
  <p>I don't want to rely on JavaMail (i.e. rely on whether my users have added the JavaMail jar to their classpath).</p>
  
  <p>I realize that I could go on and create a server for doing this and connect to it with the necessary details, but this is last option.</p>
  
  <p>How would I go on sending an e-mail in this case?</p>
  
  <p>Are there any online services etc (paid or free) that provides a solution for this? For example connecting to them and specifying recipient e-mail and message, they would handle the e-mail sending.</p>
  
  <p>Are there any smart and/or reasonably easy ways of sending e-mails using the Java Core packages?</p>
  
  <p>Thanks :)</p>
  
  <p>Mike.</p>
