mutt mailbox and procmail

[John-Mark]

Hello all I am trying to retrieve using mutt my mail from mailboxes I have
set up. Porocmail is filtering the mail and adding it to my mailbox, but I
cant see how to get mutt to see it, I have configured mutt to look in the
right places but it only ever seems to look in the default mail box
/var/spool/mail/jmj
any ideas much appreciated
thank you jm
