Maildir filenames aren't stable. I suppose you could get it working most
of the time by getting the current filename, but nothing guarantees that
it hasn't changed already by the time you're trying to open it. You
could get the current filename by using maildir-specific functions (like
maildir_file_do() where the callback function would stat() the file,
like maildir_mail_stat() works in maildir-mail.c).

You already mentioned something about using FIFOs. I'm not exactly sure
how the dspam calling works, but I think FIFOs would be the best way to
do this and also in mailbox format-independent way. If you do the spam
training before COPY command finishes (i.e. in transaction_commit()), if
something crashes in the middle you don't lose anything, because the
entire COPY operation fails, and user tries it again later.
