Re: Mutt loses mail

I can confirm that the problem does not occur when mutt is not run over NFS.

I also am 99% sure that the problem does not occur with Pine, although I can
do some more work to verify this for you if desired.

I shall try to run it under strace tomorrow.  I'm sure it will generate a
huge volume of stuff, so not sure if it will be useful, but heck, I'll give
it a shot!

I notice at this point that it doesn't use the liblockfile package that
policy heavily suggests it uses.  Policy says:

     All Debian MUAs and MTAs have to use the `maillock' and `mailunlock'
     functions provided by the `liblockfile' packages to lock and unlock
     mail boxes. These functions implement a NFS-safe locking mechanism.
     (It is ok if MUAs and MTAs don't link against liblockfile but use a
     _compatible_ mechanism. Please compare the mechanisms very carefully!)
