Antivirus and AntiSpam

At Elettra we have adopted LibraESVA as the Antivirus and Antispam software for the electronic mail service. Any user with a valid account on the e-mail server has full control on his own messages classified as spam and therefore not delivered to him, or with attachments that have been removed. This document will provide some basic intructions in order to manage those emails. If you encounter any doubt or problem feel free to contact the ICT Systems and Services via:

Virus infected e-mails filtering

Any infected email message will be cleaned and quarantined: this means you won't receive any email in your Inbox. If you were waiting for a particular mail and received nothing, please have a look at the "Spam" folder in your mail account or check your Quarantine (see "Antispam management" down below).
Potential dangerous attachments are also automatically removed from emails. You can "release" the file you are sure it's not dangerous from your Antispam management console.

Spam e-mails filtering

The e-mail messages having a very high probability to be spam will be discarded (i.e., deleted) immediately.
Those with a medium probability to be spam will be stored on a dedicated quarantine area on the Antispam Servers (see "Antispam management" down below). A copy is also delivered directly into a folder called "Spam" (or "Junk" in some email clients) in your mail account.

Antispam management

Any e-mail user with e valid account will be able to check his/her own quarantined e-mail message.
With the new MARCoNI-Z mail server, there are two methods of accessing the quarantine:

  1. all messages marked as Medium SPAM will be saved in a "Junk" folder in the mailbox and its subject will be changed to "{SPAM} <original subject>". It is possible to get to this folder both in the MARCoNI-Z webmail and in any e-mail client like Apple Mail or Mozilla Thunderbird. If this folder isn't present, check the folder subscription list in the application - actions vary from program to program, do a web search with "how to subscribe to email folders with Apple Mail" (or Thunderbird).
  2. login to with your accountname (e.g. or as username and your UniPass (VUO) password. Once logged in your quarantine area, the complete list of analysed messages will be available.webpage screenshot
  3. From the Home tab it's possible to have a view of the latest messages passed through the appliance: webpage screenshot
  4. The green envelope to the right lets you see the body of the email. The two orange arrows near the envelope will release the message: in other words, that email will be delivered to the recipient(s) if blocked or partially cleaned (i.e., attachments removed).
  5. With the Reports tab you can search for specific emails according to various criteria.
  6. In the Lists tab you can set whitelisted or blacklisted email addresses. Any address in the whitelist will be delivered regardless of the content analysis report. An address that has been blacklisted will always be blocked:webpage screenshot
  7. The Quarantine tab will get you to the list of all blocked or modified emails: webpage screenshot
  8. The Settings tab allows you to modify some changes for your account. In particular, by clicking on the pencil icon, it's possible to enable the Quarantine digest report (by default this is disabled). The server will send an email at the specified times with a list of all the quarantined, marked as spam, attachment-removed messages.

Here you can:

  1. Reply: even without releasing the message it is possible to write back to the sender from LibraESVA
  2. Download Eml: this lets you download the email in the specific eml format, useful for archiving
  3. Release message: the original message will be release from the system and delivered to your inbox
  4. Add to Whitelist: the pair sender/recipient will be automatically added to your whitelist, avoiding manual operation for this task
  5. Add to Blacklist: similar to the previous action, but related to blacklist
