sympa spool is processed alphabetically
the way sympa processes the spool/msg directory is alphabetically, which is really annoying because it will work up to the letter 'f' and then a new message will come in starting with the letter 'a' and it will immediately process that one, even though the other ones have been around for a lot longer. This makes clearing out messages that are spooled up really suckage because poor lists starting with a 'z' will take forever to eventually get processed. Sympa should figure out the dates and deal with them that way instead
