Paul, thanks for your comments. I'll go ahead with this attachment work. I'm currently merging my version of hypermail with the public one (almost done), so that we have only one CVS tree.

Note that it's important to never break URLs that point to archives. I want to add something akin to a "blackmail" file where you can put msgid's of messages that should be removed from the archive. Then, we would just skip those messages (erasing any previously related files), but correctly increment the message num counter.

I agree. I'll stick to DIR_PREFIXER/num and concentrate on some other parts of the code :)
