Mail Relaxer


Start/Stop the mail processes as needed, allowing your Syno to hibernate (sleep) in the quiet hours. Only to be used with Mail Station polling external mail server(s), i.e. NOT when you run Mail Server with own domain (because the server should keep running all the time then). Still, you can use Mail Server just as IMAP server and SMTP relay. Mail Relaxer is not intended to be used with Zarafa.

Credits for the original idea go to Tobi "jahlives" from German Synology forum.
