Added dtmail and corrected an error.
 
A = Default configuration always overrides From with Reply-To.

B = Default configuration does *not* clobber To or Cc with Reply-To

C = Default configuration ignores Reply-To if given a non-default choice at
    send time.
 
D = Reply rules can be globally reconfigured by user.

Y = yes, . = no, ? = unknown.  ?? = contributor not recorded

[1] This is shipped with Solaris 2.6.  (No, I never heard of it either :-))

[2] According to Jamie Zawinski, MH-E is an Emacs Lisp wrapper awround MH,
    but doesn't present any of MH's options for reply-rule rewriting.

[3] According to Paul Fox and Dan Bernstein, late versions of BSDmail have the
odd semantics that `r' (personal reply) ignores Reply-to, and 'R' (group
reply) honors it but also replies to To and Cc addressees.

If you submitted a report and aren't listed, let me know.

Corrections welcome.  Can anyone fill in questionmarks or add entries
for other MUAs?
