+
+* Sun YBTS daemon uses -ba. [Martin Kiff <MGK@newton.npl.co.uk>]
+
+* EXPN adds @domain to all mailers, including prog. Is this right?
+ [Bob Henry]
+
+* EXPN adds @localhost instead of @$M. [Pel Emanuelsson]
+
+** [AEJ] You can use symbolic links to point into protected directories.
+
+* 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.
+
+*** Dynamically allocate MAXNAME buffers for headers.
+
+*** 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.
+
+* Some way to relay unfound local users to another site.
+
+* Disable all default RW sets except mailer-specific?
+
+** Extend OI to allow separate settings for canonification, MX, and A
+ lookups.
+
+** Add $!x class to match any number of words not in class x [KRE].
+
+**** Change NoReturn to be an envelope flag.
+
+**** Add M_NOLOOPBACKCHK (k) mailer flag to turn off check of name in
+ HELO command.
