First we had the CHRISTMA EXEC, and now we have the DIR EXEC. Both
have had a negative impact on the network. Fortunately, both have not
been as serious as they had the potential. In both cases, explosive
propagation has been done via NAMES files, but I know of no case in either
where one of those NAMES files caused distribution over a major Listserv
List. However, it is only a matter of time. While far from perfect, I
would like to propose a method for slowing its distribution. I would
propose a new postmaster command BLOCK. The syntax would be:
BLOCK FN=filename filetype
This filename filetype would be recorded, and any files to be
distributed would be checked against this list. If found,
the file should be held and a note sent to the postmaster.
This is obviously a very rough proposal, which is why I've sent it to the
list for further discussion, rather than directly to Eric and Turgut.
Several questions I can see:
- How to unblock a file(another command, or a syntactic option?
- Are there other attributes to block against than filename filetype?
- How would a postmaster say its ok to process this?
- Should there be an option to search all spool files in the
system to id those with fn-ft of block files.
- Should it be extended from just postmasters to other users? Which
others? List owners? Other postmasters from PEERS NAMES?
