Here are some suggestions:

  1. For ease of file management, our local modification of v1 used a subdirectory tree for attachments. If message 0123.html had attachments, for example, they'd be put into a archive/.attachments/0123/ directory. This would have the side benefit of limiting the scope of potential mischief.
  2. If it is desired to keep attachments in a flat directory with the archive, a specific set of names (.htaccess is the only one that jumps out at me, but no doubt there are others) could be excluded.
  3. The local sysadmin could touch an .htaccess file and set the permissions such that hypermail could not overwrite it. Similarly, for any other reserved names.

Item (2) might still be desireable if (1) is implemented, to protect the .attachments/NNNN/ subdirectories.
