Operating Principles

The Dr.Web Mail Quarantine component serves two main purposes:

•Storing message queues and metadata on the hard disk during Dr.Web MailD message scans. Email messages are stored as files; their metadata is stored in an SQLite relational database. Storing of messages is required for SMTP and BCC modes.

•Redirection of a message to the Dr.Web MailD component after a certain time-out if an error occurs during the message processing (for instance, if the message could not be resent). The component ensures that the processed message gets delivered to the МТА.
