Searchable Logs - Expected an email that you didn't receive? Check log files to see what happened.
Message Queuing - If your mail server goes down, mail will be queued until the mail server is available.
User Based Reports - Enable reports for specified users, contains total filtered emails and total email processed.
Whitelist - Per User whitelist, if an email address gets filtered that you are sure should be allowed, add it to the whitelist.
Blacklist - Per User blacklist, stop all email from a particular email address. These emails won't even be quarantined.
Report Spam - You can train the filtering service, if you receive a spam email it can be uploaded to your filtering service.
Spam Quarantine - If our advanced spam filtering system considers a mail spam, it is placed in your spam quarantine folder.
How it works :
Your email passes through automated spam filters that detect suspected junk email and viruses, based on your personal preferences.
Blatant spam is removed automatically, while suspicious email is directed to your own web-based quarantine folder (it does not arrive at your computer's in-box).
Additionally you can "block" senders using the blacklist; meaning, email from them will always be filtered. Or you can "approve" senders using the whitelist; meaning, their email will always be delivered.
