Hi, I a kind of new to java mail programming and I am used to develop on a windows platform. I understand that you need a smtp server for sending mails ( of course). In a unix environment one can use 'sendmail'. But I do not see how to use it in my implementation. What do I fill in in the properties I pass to the session, when it comes to defining the smtp server when using 'sendmail'? Properties props = new Properties(); props.put("mail.smtp.host", ???); Session session = Session.getDefaultInstance(props, null); thx, Michel.    More>>

			

			Properties props = new Properties();
			

			props.put("mail.smtp.host", ???);
			

			Session session = Session.getDefaultInstance(props, null);
