	  leak.

	  structure, so call to server_kill_clt should be called first.

	* server/client.c: removed useless ops in client_deregister- client
	  & clients are both local automatic to the routine, so setting them
	  to null before returning is pointless.

	  RETR if HAVE_POP3_TOP is defined; reduces load on server by not
	  getting whole message just for subject lines.

	* clients/zmailnotify/zmailnotify.c: added POSIX file locking,
	  ifdef'd on _POSIX_SOURCE

Thu Feb 13 02:38:10 1992  Lucien W. Van Elsen  (lwvanels at godtree)

	* server/kstuff.C (SendKerberosData): Changed so that Kerberos error
	message are sent with the Kerberos error base added to them; the
	routines in bdump.c which use SendKerberosData were changed to uses
	error_message() to decode the error returns from

	supression code.
