Anti-spam checking

Incoming messages are checked for spam or malware by appropriate anti-spam appliances. Dangerous messages or messages clearly identified as spam are deleted or quarantined. You will be informed about quarantined e-mails on a daily basis, if necessary.

Alternatively, you can use the anti-spam appliances to find out about quarantined (Mail quarantine menu item) or rejected e-mails (Mail log menu item), to release e-mails from quarantine, and to maintain a personal white and black list.
