    1. Purpose

    The file with the list of unnotificable viruses allows to blocks notifying
to specified person (sender, recipients or admin) depending on virus name.        
    
    The lines starting with # character are considered commentaries and
therefore get skipped, blank lines are also admissible. If the first
meaningful line contains the alike record:

[version=NN]

it means that the records are kept in the NN-version  of the file. If
there is no such a line the file is reputed as written in the  of the
1st version.


    2. Version 1 

TO_ADMIN TO_SENDER TO_RCPTS VIRUSNAME
...

    TO_xxx - { allow | deny } (i.e. either allow or deny value).
specify can filter send notify to person or not.    
    VIRUSNAME - virus name. All virus names should be written in terms of POSIX 
regular expressions.  For example name HLLM.Generic.95 should be written as 
"HLLM\.Generic\.95". Also strongly recommended to enclose all name to quotes.
Regular expression is case insensitive.


    3. Version 2 

TO_ADMIN TO_SENDER TO_RCPTS QUARANTINE VIRUSNAME
...

    QUARANTINE - { allow | deny } This parameter allows to prevent from
moving message infected by VIRUSNAME to quarantine. It's useful during
epidemies of viruses these forge sender address.


    4. Interpretation features in case "cure", "remove" and "redirect" actions.

 * if actions "cure" or "remove" are specified, virus is removed (for some
types of viruses, i.e. trojans, cure is equal to removing) and notification
to recipients is blocked then action "discard" (or "reject" if "discard" is not
supported by MTA) is applied.
 * if action "redirect" and quarantine function is blocked for this virus
then redirection is not performed and action "reject" is applied.
