Gnus corrupt mailbox w/ nnml

[Kyle Sexton]

All,

I'm trying to convert to using nnml since nnmaildir was *slooooow*.
Everything I've read says that nnml is the fastest backend for Gnus
since it is the most like an actual news server.  My setup consists
of:

fetchmail -> procmail -> Inbox.spool

When I try to start Gnus I get an error:

Error, unknown mail format! (Possibly corrupted buffer ` *nnmail
incoming*'.)

I then get stuck w/ an ~/.emacs-mail-crash-box, but whatever I do I
can't actually view the messages.  I ran the file command on the spool
and got the following back:

Work.spool: ASCII mail text

Here's the contents of my procmailrc and .gnus

.procmailrc
MAILDIR=$HOME/Mail
DEFAULT=Work/Inbox/

# Catchall to the inbox
:0:
/home/user/.incoming/Work.spool

.gnus
(setq
 gnus-secondary-select-methods '((nnml ""))
 mail-sources '((directory :path "~/.incoming/" :suffix ".spool"))
 mail-source-delete-incoming t
)


Thanks in advance for any advice.
