Are the e-mail alert and e-mail backup features not currently enabled in build 4.720? If not, then I don't think mine is working. I get the backup e-mailed manually if I manually click the start button for the backup. However, I do have it set for "E-mail backup daily", but I've yet to recieve an automatic e-mail with the backup file like I did with v4.
Also, when using v4.021, a visit to www.grc.com (shields up test) and http://www.pcflank.com/exploits.htm would cause Astaro to fire off Port Scan Detected e-mails which included IP address, time, ect. I've visted both of these sites and done the usual tests (which BTW, v4.720 passes with flying colors) but have never recieved an e-mail alerting me to the scan/attempted break in.
