As an Administrator, you can access the Email Quarantine for the entire domain. The Email Quarantine displays spam emails that have been filtered by our content filters. These are emails that are considered spam, virus infected, or have been blocked by blacklistings set by yourself or your domain administrator.
By clicking on the tabs you can view the different types of quarantined emails:
Spam - email is considered spam by content filters. A standard spam score is 7 unless your settings have been changed
Virus - email has been identified as infected with a virus or malware.
Banned- emails with banned filetypes are messages that contain various types of dangerous enclosures. The standard filetypes blocked by this filter include: .bat, .cmd, .com, .cpl, .dll, .exe, .pif, .scr, .js, .jar and .vbs.
These restrictions apply to files embedded inside other files, like zip or tar files too.
Bad MIME - The MIME structure of the email violates the standards. This may be an attempt to exploit vulnerabilities in email clients.
Unchecked - The email could not be checked because it is encrypted, or contains an enclosure that is encrypted or password-protected.
Deleted - when you delete an email in the spam tab, it is transferred into the Deleted tab.
Recovered - when you recover an email that is considered a false-positive, the email is transferred into the Recovered tab.
Blocked - emails that have been blocked by a user or in the domain-wide settings are listed here.
Working With Emails in Quarantine
Emails in quarantine can be actioned in several ways if needed. Select an email in the spam tab by clicking on the subject or by clicking on the checkmark.
Delete - this will move the email from the Spam tab to the Deleted tab. The email will remain in the Deleted tab until the quarantine is flushed every 15 days or so.
Recover to Mailbox - if an email in the Spam tab is considered a false-positive, select to receive in your inbox
Recover & Whitelist Sender - if the email is a false-positive and you would like to whitelist the sender, select this. *Caution* Keep in mind that whitelisting means you wish emails from this sender will always bypass our filters so we recommend using this option only for a very few known and trusted senders.
Whitelist Sender - selecting this means emails from this sender will always bypass our filters so we recommend using this option only for a very few known and trusted senders. If possible whitelist by a more secure method using both the IP/Server and email address.
Viewing the Email Details in Quarantine
If you would like to see the full header or more details of the email, click on either the Sender or Subject of the email. There will be a pop up window containing the entire email.
If you need the full header which includes the content filtering spam score details, click on All Headers.
The detail in the Full Header contain all details of the date, time, sender, recipient as well as mailserver information. You will also see details of the X-Spam-Status indicating the filter scoring which caused the email to be quarantined.
Quarantined emails are stored for a minimum of 15 days.
