Dear all,
I am evaluating exim in order to
replace sendmail on standalone personnal stations
(sendmail follows the MX records and we don't want to do that
inside our domain).
In this context I don't know :
"How to remove the Sender field when sending a message"
When using smail : remove_header=Sender
(smtp transport in the transport file)
-------------------------------------
Here are more details (rather long, to validate the request) :
I'd like to remove the Sender field, because it represents
user@??? (1) while the From field is rewritten into a more
generic form FirstName.LastName@??? (2)
(1) isn't reachable by mail from the outside world
because our central mail system (still not running exim ... but maybe in
the future :-) ? ) is allowed to send mail
only to a few "secure" computers. Then people get their mail
via POP3 to their stations. To send they masquerade the From
field so that it looks like user@???.
that is rewritten by the central mail server into (2)
The problem is that RFC-822 states :
-----------------------------------------------------------------
The "Sender" field mailbox should be sent notices of
any problems in transport or delivery of the original
messages. If there is no "Sender" field, then the
"From" field mailbox should be used.
-----------------------------------------------------------------
If the Sender is not reachable, this is a real problem, isn't it ?
---
Later I could setup exim so that Sender = From (and still exists)
but in that case RFC-822 states :
-----------------------------------------------------------------
4.4.2. SENDER / RESENT-SENDER
This field contains the authenticated identity of the AGENT
(person, system or process) that sends the message. It is
intended for use when the sender is not the author of the mes-
sage, or to indicate who among a group of authors actually
sent the message. If the contents of the "Sender" field would
be completely redundant with the "From" field, then the
"Sender" field need not be present and its use is discouraged
(though still legal).
