(Version 8.8 of 10/31/93)

Key:
  X -- extension (user visible change)
  B -- bug fix
  S -- security fix
  E -- enhancement to existing algorithm

X ****	8 -> 7 bit MIME conversion.

E ****	Change NoReturn to be an envelope flag. [8.7]

X ****	Add M_NOLOOPBACKCHK (k) mailer flag to turn off check of name in
	HELO command. [8.8]

X ****	Merge Sun changes.  [8.7]

X ****	Provide a way to turn off all DNS lookup in the I option, e.g.,
	``OIoff''.  [8.7]

X ****	Should have new mailer flags to override LocalMailer stuff:
	- M_ALIASABLE (A) -- can use as the LHS of an alias.
	- M_HASPWENT (w) -- should have a /etc/passwd entry.  If not found
	  there, implies user unknown.  Also implies .forward and UDB
	  searching, search for |, /, and :include:, etc.).
	- Actually, UDB searching and |, /, and :include: mapping should
	  probably be on another flag.  (Cannot be 'l' for back compat
	  reasons.)
	- Need for $@host part of triple and Return-Receipt-To: processing
	  should also be split apart.
	[8.8]

E ****	Fix parseaddr to return a dummy mailer with QBADADDR set for
	all cases except null input; change calls to be more sceptical
	about the return value, checking this bit instead of just
	checking for == NULL.  (Eric Wassenaar)  [8.7]

X ****	Run time configurable locking -- e.g., compile in HASFLOCK and
	HASLOCKF, and then choose at runtime between these.

E ***	Dynamically allocate MAXNAME buffers for headers.

X ***	Add ability to disable Return-Receipt-To: on a privacy flag. [8.8]

X ***	Add -P to set precedence (e.g., -Pbulk). [8.8]  (BCX)

X ***	Runtime option to enable/disable IDENT protocol.

E ***	Don't send ErrMsgFile to postmaster bounces.  (Josh Smith,
	josh@osiris.ac.hmc.edu).

X ***	Add "user" map to look up a user name via getpwnam -- so that
	non-local names can be forwarded to another site.  [8.8]

E ***	Have daemons that start up check the alias database for
	correctness and auto-rebuild if necessary.  This is to handle
	the case of a system crash during an alias database rebuild.

E ***	Eliminate E qf line and e_errorqueue; use e_errorsto a la
	e_receiptto.  This simplifies and gives symmetry.  (Eric
	Wassenaar)

X **	Allow $x in -bt mode to expand macro "x".  (BCX)  [8.8]

X **	Allow /address in -bt mode to expand address through ruleset 0,
	aliases, etc. and display results.  [8.8]

X **	"R mailer address" in -bt mode does remotename on address.

E **	Adjust "infinite loop in rule" code to handle entire ruleset
	(Code from Michael Corrigan).

E **	Allow :include: from command line (not SMTP) to assist in
	"personal list" management -- i.e., creating lists that
	cannot be EXPNed.

X **	Database (keyed lookup) auto-rebuild.

X **	Find a good test suite and include in the distribution.

S **	You can use symbolic links to point into protected directories.
	(AEJ)

X **	Extend OI to allow separate settings for canonification, MX, and A
	lookups.  [8.8?]

X **	Add $!x class to match any number of words not in class x. (KRE)

X **	LOCAL_RULE_5 (Spencer Sun, spencer@phoenix.Princeton.EDU)

X **	Add "bestmx" map -- returns "best MX host" for this address.
	Allows you to do automatic detection of when you are the best
	MX for a given address.  [8.7?]

X **	Extend makemap to "gather" values -- i.e., merge entries that
	have the same keys. [8.8]  (BCX)

E **	Allow error messages on individual addresses in the qf file.
	(BCX)

X **	Multi-character option names.  [9.1]

X **	User database extensions for mailing lists:
	list:precedence -- Precedence: value for new message
	list:envelopefrom -- envelope "from" value for new message
	others?  [8.8]

B **	Restore `T' line to eliminate X-Authentication-Warning: at
	inappropriate times.  (Christophe Wolfhugel)
	- T could become a shorthand for Ct -- i.e., create a new
	  predefined class.
	- Eliminate "<user> set sender to <address>" message entirely?
	  (this is the workaround)

X *	-V flag to print state of all (?) compilation flags.

X *	Handle Expires: header field (if still in queue).

X *	WIN/3B support (non-atomic rename, no h_addr_list, others?)
	(Bruce Lilly <blilly!bruce@uu.psi.com>)

X *	Sun YBTS daemon uses -ba.  [Martin Kiff <MGK@newton.npl.co.uk>]

B *	EXPN adds @domain to all mailers, including prog.  Is this right?
	[Bob Henry]

B *	EXPN adds @localhost instead of @$M.  [Pel Emanuelsson]

E *	Change body put code to time out around individual puts.  This will
	make the timeout algorithm more responsive and more resilient.
	Unfortunately, it's also a pain in the butt.

X *	Some way to relay unfound local users to another site.

X *	Disable all default RW sets except mailer-specific?
