File locking broken with 2.99.45 on FreeBSD 2.1

[alcocer@netcom.com (Dario Alcocer)]

Is anyone using ZMailer on FreeBSD?  I've installed it on my PC,
486DX80 with 32MB.  After installation, I tried testing it by sending
a message to another local address, but I did not see the message
delivered to the local mailbox, nor did I recieve a bounce message.

I went rummaging in $POSTOFFICE/queue to see if I could figure out
what went wrong, and I found this in one of the message files:

    % channel error
    % todsn ORCPT=rfc822;postoffice
    % to <postoffice>
    % env-end
    % To: dummy:; (error trapped source)
    % From: The Post Office <postmaster>
    % Sender: mailer-daemon
    % Subject: Double-fault: Delivery reports about your email
    % Cc: The Post Office <postoffice>
    % MIME-Version: 1.0
    % Content-Type: multipart/report; report-type=delivery-status;
    %         boundary="A41C6D020.854311499=_/pino.connectnet.com"
    % 
    % --A41C6D020.854311499=_/pino.connectnet.com
    % Content-Type: text/plain
    % 
    % This is a collection of reports about email delivery
    % process concerning a message you originated:
    % 
    % <local root alcocer 0>: can't dotlock "/var/spool/mail/alcocer": Permission deni
    % ed (this is abnormal, investigate!)


How should file locking be configured on FreeBSD?  In case it matters,
I *was* running 2.99.26 with HOSTENV (in Config) set to FreeBSD-2.0,
and I was not encountering file locking problems before.

Any advice/suggestions appreciated.
