Write protected mailbox problem

[Joakim Svensson <jocke1s@brizo.tripnet.se>]

Hi all,

Just a short question about mail.

I am using exim/fetchmail/mutt
I have all mail from the debain lists going into
a mailbox "debian-user". This is done with a .forward
file in my home dir.
Fetchmail is run every 3 minutes or so whenever I am
hooked up to my provider.

Now I sometimes have problems deleting mails in this
mailbox.
I guess it could be related to that fetchmail is writing
to the file while I am using mutt to read/delete mails
at the same time. Even though I have this problem sometimes
when I am not connected to the internet and fetchmail is
not running.

Is there a way to solve this problem ?

Best regards
Joakim Svensson
