Re: [nail-devel] "from" variable not working for rejections

[Steffen N. <st...@sd...>]

Hello Felipe.

First: i am the maintainer of a fork of the software discussed
here.

I have hopefully improved the manual of my fork even more, and
also have added a *r-option-implicit* variable so that the
automatic deduction via *from* (or *sender*, if *from* contains
multiple addresses) can be achieved without using command line
options [1].  I have given you credit for that, of course [2].
The manual now reads

  If the given from-addr is valid then it specifies the envelope
  sender address (used to report, e.g., message bounces) to be
  passed to a file-based mta[378] (Mail-Transfer-Agent) as ‘-f
  address’ when a message is sent.

and

  Note that S-nail by default, without -r that is, neither passes
  -f nor -F flags to a file-based MTA by itself.  One may also
  set[190] r_option_implicit[416] to gain the automatic deduction
  (only) without an explicit -r[64] command line option.

and (under *from*)

  If a file-based MTA is used, then from[346] (or, if that
  contains multiple addresses, sender[430]) can nonetheless be
  forced to appear as the envelope sender address at the MTA
  protocol level, either by specifying an empty -r[64] command
  line option, or by setting the variable r_option_implicit[416].

and

  r_option_implicit
    (Boolean) Setting this option evaluates the contents of
    from[346] (or, if that contains multiple addresses, sender[430])
    and passes the results onto the used (file-based) MTA as
    described for the -r[64] option (empty argument case).

which i hope is an improvement, all in all.

  (Note these URLs are not stable, it is a development branch.)
