Hi minis minis said: Rejected email are not traced in the log viewer , however delivered email are traced The XG's log viewer is still not 100% satisfactory, Sophos still needs to do some work on this, there is also a lot of talk in the community about this topic. Unfortunately you don't get that much information from Sophos in advance about future releases of the log viewer. Maybe there will be improvements in the 18.5, maybe not... 
 But you have the possibility to do detailed logging analysis. In the admin settings of your XG appliance at SYSTEM > Administration > Device access , enable the SSH function in the LAN or VPN zone and log on to the XG via ssh with the admin user: ssh admin@IPOFYOURXGFIREWALL 
 Then go via 5 (Device Management) and 3 (Advanced Shell) to the advanced CLI. You can now search for the mail and see why Sophos rejected the mail by using: cat /log/smtpd_main.log | grep your@mailsender.com 
 If the reason for the rejection is not immediately obvious, you can provide the excerpt from the log file here in the thread. Please keep in mind that private information (e-mail addresses and IP addresses) should be censored.
