+# Spam
+
+SnappyMail relies on the anti-spam features of the mail server.
+
+The spam bar, shown in messages, is based on several mail headers, generated by: SpamAssassin, Rspamd or Bogofilter.
+
+When the mail server is properly configured:
+* Moving a mail to Spam folder will instruct the mail server to learn from the message as being spam.
+* Moving a mail from Spam folder to an other folder will instruct the mail server to learn from the message as not being spam.
+
+
+# Virus
+When ClamAV is installed and integrated on the mail server, SnappyMail can show if a message contains a virus.
