Azzaron uses a sophisticated AntiSpam engine to help keep users safe and inboxes free from dangerous viruses.  It may block content it calculates to be unsafe.  When a file is blocked but not necessarily recognized as spam, the user will receive a warning email.

A message may be received with an attachment looking like the following:

This warning indicates that the system detected a dangerous attachment.  But since the system was not able to determine if the attachment is spam, the warning is sent to the recipient.  There is no danger opening or otherwise viewing this warning attachment.

If this is an important attachment and you recognize the sender and the file, then contact the Azzaron helpdesk so they can help you retrieve that file.  However, most of the time, the attachment actually is a virus, some other malicious file, or questionable content, so no further action is needed by the user.

These messages are held in the quarantine for three weeks if manual retrieval must be done.  After that time, it is impossible to retrive quarantined files.

As an example, the body of the warning email will look similar to this:

Subject: [Blocked Content] Original Subject Line
Warning: This message has had one or more attachments removed
Warning: (not named).
Warning: Please read the "/reports/Azzaron-Attachment-Warning.txt" attachment(s) for more information.

Opening the attachment warning text file is not dangerous. Inside, it will be formatted similar to the following and help Azzaron techs figure out why your email was blocked:

This is a message from the MailScanner E-Mail Virus Protection Service

in your request. Alternatively, you can call them, with
the contents of this message to hand when you call.
