Quarantined E-mail Appliance (SPAM FILTER)
Wooster has deployed a spam and virus filter for incoming email messages. Each message gets a score based on criteria set by Xecuritas, our Spam filter provider, and if a message scores high enough, it is quarantined by the filter. Users can login and view, delete, forward, trust, or block each message depending on the content of each message. This document outlines how to manage email quarantined due to viruses and/or spam.
Any email with an attachment file type of .exe, .dll, .pif, and .bat will be automatically quarantined. Virus transmission through email is a significant problem and these file types are targeted specifically because they are the most popular file types used for viruses. They are also not typically exchanged via email for any other purpose.
Users can access these quarantined messages by visiting: https://messagescreen01.wooster.edu/user/index.php and entering their full email address (email@example.com) and email password.
Once they have logged in, all quarantined messages will be listed. The user will have the option of releasing a quarantined message to their account (see screen below). If a user does not release the message, it remains quarantined for seven days and is then deleted.
You can check this screen as often as you like. If you release a message to your email account, please be aware that it may still contain a virus.
Spam is defined as unsolicited email. There are some consistent features of spam that can be used to filter out this kind of email at the server-level.
Due to the way a spammer sends a message, the name in the From field is not a valid email address. You can see this if you click “reply” on a spam email because the To field will be blank. In addition, other parts of the email that the user sees do not match the information sent from the spammer’s server to the Wooster email server.
To help cut down on these emails, the College has implemented a spam filter. This device has a list of criteria it uses to score an email on a spam scale. If the message obtains a high-enough score, it is quarantined.
Through the web site mentioned above, you can also view email quarantined as spam. Going to https://messagescreen01.wooster.edu/user/index.php and logging in will allow you to view the list.
In the top left corner of the window is the legend for the symbols next to the message.
You can choose to:
- View the message
- Release the message (sends it to your email client)
- Release & Whitelist (any message from that site will automatically come through the filter)
- Forward the message to a different email address or delete the message.
If you do not delete a message, the system will do so for you after seven days.
The release and whitelist option adds the email address to your list of trusted senders. Trusted senders are senders you have flagged as mail that should come through the appliance. The more trusted senders you have, the more opportunity you have to receive a virus.
Another way to add trusted senders is by clicking on Trusted Senders on the left side of the window. From here, you can click on Add Trusted Sender. Enter either the email address of the individual (firstname.lastname@example.org) or the domain name (@something.xxx without a user name).
MessageScreen provides a notification option for all users. On the left side of the screen, you will see User Settings. This page contains a variety of user options, including a Quarantine Summary email.
You can define if and when you receive an email notification about the contents of your quarantined mailbox.
