Problem with NFS-mounted mailboxes

[Christoph Maurer <christoph-maurer@xxxxxx>]

Hello mutt users!

I'm using mutt on a SuSE 9.1 distribution. 

My home directory is mounted via NFS. Since having installed SuSE
9.1, I can only write my mailboxes when starting mutt on the machine
where my home directory is located physically. On all other machines
mutt opens my mailboxes only in read-only-mode. 

I assume this is a locking problem but tried several compilation
modes and could not fix it. 
Last tested version is 
System: Linux 2.6.4-54.5-default (i686) [using ncurses 5.4] [using libiconv 
1.7] [using libidn 0.3.7 (compiled with 0.3.7)]

Any ideas how I could go on?
