This is not an ``even better way'' for me because: Each single digest
message represents perhaps a couple dozen messages, if these messages
were to be processed one at a time.
I dont want the server on my ISP processing hundreds of messages a week,
and I dont want yarn's import command processing hundreds of messages
either. The reason is the same in both cases: On the surver side,
the more message traffic I get the greater the chances of mishaps with
locfiles, procmail, software downtime and other typical server-related
mail problems (of which my Verio company has plenty).
I have also found yarn's import command to be somewhat unreliable when
processing large files or large volumes of messages in a single file.
For me and others, errors and corrupt files occur with some frequency.
For all these reasons, I would rather move one (digest) file all the
way to a yarn folder, and then split it up using programs I trust.
