Remove certain headers using mailx or sendmail
Hello,
So i want to send mails in any way from a solaris 5.8 system, perhaps using mailx or sendmail. My purpose is to stay clear of systems name in head data. So i want to strip at least the "Message-Id" and the "Recieved" headers of the mail. Yet this seems to be a bit of a problem.
Now i have seen mails earlier with no headers at all (besides subject), this could also be an option, just to remove all headers. Can anyone help me out?
(this is not intended for spamming purposes, my firm wants to mailout a bunch of mails each day automatically, to our customers, direct from core production enviroment, yet we dont want to reveal core system server name, eventhough its protected by firewalls etc.)

regards

LEARN ABOUT FREEBSD
mailer.conf
MAILER.CONF(5) BSD File Formats Manual MAILER.CONF(5)
NAME
mailer.conf -- configuration file for mailwrapper(8)
DESCRIPTION
The file /etc/mail/mailer.conf contains a series of lines of the form
name program [arguments ...]
The first word of each line is the name of a program invoking mailwrapper(8). (For example, on a typical system /usr/sbin/sendmail would be
a symbolic link to mailwrapper(8), as would newaliases(1) and mailq(1). Thus, name might be ``sendmail'' or ``newaliases'' etc.)
The second word of each line is the name of the program to actually execute when the first name is invoked.
The further arguments, if any, are passed to the program, followed by the arguments mailwrapper(8) was called with.
The file may also contain comment lines, denoted by a '#' mark in the first column of any line.
FILES
/etc/mail/mailer.conf
EXAMPLES
This example shows how to set up mailer.conf to invoke the traditional sendmail(8) program:
# Execute the "real" sendmail program located in
# /usr/libexec/sendmail/sendmail
sendmail /usr/libexec/sendmail/sendmail
send-mail /usr/libexec/sendmail/sendmail
mailq /usr/libexec/sendmail/sendmail
newaliases /usr/libexec/sendmail/sendmail
This example shows how to invoke a sendmail-workalike like Postfix in place of sendmail(8):
# Emulate sendmail using postfix
sendmail /usr/local/sbin/sendmail
send-mail /usr/local/sbin/sendmail
mailq /usr/local/sbin/sendmail
newaliases /usr/local/sbin/sendmail
This example shows how to invoke a sendmail-workalike with Exim (from ports) in place of sendmail(8):
# Emulate sendmail using exim
sendmail /usr/local/sbin/exim
send-mail /usr/local/sbin/exim
mailq /usr/local/sbin/exim -bp
newaliases /usr/bin/true
rmail /usr/local/sbin/exim -i -oee
This example shows the use of the mini_sendmail package from ports in place of sendmail(8). Note the use of additional arguments.
# Send outgoing mail to a smart relay using mini_sendmail
sendmail /usr/local/bin/mini_sendmail -srelayhost
send-mail /usr/local/bin/mini_sendmail -srelayhost
SEE ALSO
mail(1), mailq(1), newaliases(1), mailwrapper(8), sendmail(8)
postfix(1) (ports/mail/postfix), mini_sendmail(8) (ports/mail/mini_sendmail)
HISTORY
mailer.conf appeared in NetBSD 1.4.

BUGS
The entire reason this program exists is a crock. Instead, a command for how to submit mail should be standardized, and all the "behave dif-
ferently if invoked with a different name" behavior of things like mailq(1) should go away.
