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

INCM(1) General Commands Manual INCM(1)
NAME
incm - Incorporating new mails for Mew
SYNOPSIS
incm [options]
DESCRIPTION
The incm utility incorporates new mails from the mbox or the maildir to Mew's inbox folder.
The options are as follows:
-a Retrieve all mails from maildir/{cur,new} for maildir.
-b Backup mails. mbox: No truncate mbox file. maildir: To maildir/cur directory.
-c Use the Content-Length: field, instead of the "From " line, as a mail separator for mbox.
-d path Path to mbox/maildir. If path is a file, mbox is assumed. If path is a directory, maildir is assumed.
-m path The same as the -d option.
-s Read one mail from stdin instead of mbox/maildir.
-i inboxdir
A path to the inbox directory.
-u Don't touch ".mew-mtime".
-f Preserve Unix From (Envelope Sender) line in mbox case.
-p mode Specify file mode that creates in mbox case.
-o Use the suffix when creating messages.
-x suffix
Use this suffix.
-h Display this help message.
-v Display the version.
mbox
For mbox, the mail separator is "From " in the beginning of lines. The incm utility does not convert ">From " to "From " in the beginning
of lines in the body. On Solaris, Content-Length: should be used with the -c option to tell the end of mail.
To lock mbox, a lock file("<user>.lock"), flock() or lockf(), and open(O_EXLOCK) are used.
maildir
For maildir, no lock and no separator are necessary.
Consider the following situation:
cur/{1,2}
new/{3,4}
Executing incm without the options results in:
cur/{1,2}
new/{}
to inbox: {3,4}
Executing incm with the -a option results in:
cur/{}
new/{}
to inbox: {1,2,3,4}
Executing incm with the -b option results in:
cur/{1,2,3,4}
new/{}
to inbox: {3,4}
Executing incm with the -a option and the -b option results in:
cur/{1,2,3,4}
new/{}
to inbox: {1,2,3,4}
So, if both options are specified, messages are retrieved multiple times.
