Mail not appending to mbox

[alani]

hi Nancy. The procmail tutorial was very helpful, but I can't get over
one last hump.

I want new messages to be appended to my Unix format mailbox
~/Library/Mail/IMAP_MAIL_STORE/myName instead of /var/mail/myName , but
I can't figure out how to accomplish this.

MAILDIR=${HOME}/Library/Mail/IMAP_SERVER_STORE

# This didn't help
## DEFAULT=${HOME}/Library/Mail/IMAP_SERVER_STORE

# check for spam
:0fw:spamassassin.lock
| /usr/bin/spamc -f

# Tried adding the following to no avail
## :0:
## ${MAILDIR}

What do you think?

LOGNAME. Oh, that was painful. I needed to do a lot of careful reading
to weed that out.

I added this line:
DEFAULT=${HOME}/Library/Mail/IMAP_SERVER_STORE/$LOGNAME
Do I also need to add:
:0:
${DEFAULT}

Or is that action automatic?
