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 checks. Email messages are stored as files; their metadata is stored in the SQLite relational database. Message storing is required for the SMTP and BCC modes.

•Redirection of a message into 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 guarantees that the processed message gets delivered to the MTA.

The Dr.Web Mail Quarantine component cannot be launched by a user. It is launched automatically by the Dr.Web ConfigD configuration daemon when receiving requests from other components.
