Hi,
This is a slightly shorter version of some questions I asked earlier
regarding smail configuration. I've read all the smail docs available
and there is no definitive smail resource, so I'd really appreciate it
if someone would *PLease* take a few moments to reply.
1.) How can I find out what ident_sender, as well as all other
variables, are assigneded as? (I need to know so I can test what is
happening; e.g.: when I set visible_name to u.washington.edu, and
restart smail and inetd or reboot, there is no change, but I don't know
why. I've tried echoing and mailing the variables, but I must be doing
it wrong.)
2.) Why does "from_field" require it begin "From:" (as shown in the man
page below) and does "from_field" rewrite the "From:" line, or the
"Sender:" line and how does it decide? (It seems ambiguous.)
8<------------------- man smailconf(5) --------------------->8
from_field
type: string
This string will be expanded to form From: or Sender:
fields. The expanded string must begin with "From:",
which may be replaced by other strings to form an
actual header field. The default value is:
From: $sender${if def:sender_name: ($sender_name)}
8<---------------------------------------------------------->8
3.) What is the difference between the roles of Sender:, Return-path:,
and From: lines and are each required according to RFC's? (It was my
understanding that there was some contention as to whether the Sender:
line was required, but that it was desirable because it acts as an
"envelope", which is a good thing for some MTA's and MUA's. I'm not
clear about the roles of Return-path:, From:, and Sender: or which are
required.)
Any help would be greatly appreciated.
