[Evolution] Accessing remote mailboxes

[Bryn Jeffries <b jeffries1 physics ox ac uk>]

I originally ran the version of evolution bundled with Redhat 8.0 (Ev
1.0.4?). This was set up to collect mail from the home directory of
another linux box, which I was connected to via Samba.

Hence, Evolution would look at /home/me/othermachine/maillink
where othermachine was an smb mounted directory to me othermachine 
Maillink itself was a symlink to /var/spool/mail/me on othermachine.

This may sound complicated, but it is the most expedient arrangement for
my situation, and it worked. However, upon upgrading to Evolution 1.4.3,
I now receive an error each time I check for mail:

        Error while 'Fetching Mail':
        Could not lock '/home/me/othermachine/maillink'

Do I take it that some file-locking procedure is now being used? If so,
is there a way around this? In the previous version of Evolution the
contents of /home/me/othermachine/maillink were simply removed from the
file and imported to the local Inbox. I have tried both "local delivery"
and "Standard unix mbox spool" in settings -> receiving mail -> server
type options. "Local delivery" gives the above error, whereas the spool
option does not appear to do anything (no error, but no new email
either).
