Setting proper From host in Sendmail
Pardon me if this is OT, but it is probably an easy question for many on this list. The problem: Host on my Internal network sends out formmail replies as FROM www.thehost.com QUESTION: How can I make it show the replies as being from the sender -- my web forms provide for picking up the From field. If I test this on my gateway/router machine, it inserts the right FROM info as [EMAIL PROTECTED] instead of the www. Is there some setting in Sendmail that will make that machine (aliased on the LAN) over-ride the www and use the proper From field of the sender...??? Appreiate any help on this as I need the proper From so that the auto-responder can send out automatic replies to the customer. Best regards, Jack L.

Add: MASQUERADE_AS(`somewhere.net')dnl ...to your sendmail.mc (perhaps /etc/mail/freebsd.mc). Other options, like masquerade_envelope, might also be required, but that's the place to start -Chuck -Chuck To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

I don't want the FROM to be replaced with the machine's host name, but the FROM field of the customer who fills in his email address in the web form. In other words, the system isn't seeing that field and is replacing with the [EMAIL PROTECTED]. That's the only way my vacation program can send an autoreply to the customer. What you suggest will just send the autoreply back to the machine it came from. Any other thoughts...?? Sorry if this is not clear. Best regards, Jack L.

What you suggest will just send the autoreply back to the machine it came from. perldoc -q Mail returns some useful suggestions. I'd recommend using Mail::Mailer instead of formmail.pl, because the latter has had a iffy security record. If you feed the message into sendmail directly (as the example shows, or via vacation, for that matter), you can use the -f option to sendmail: -fname Sets the name of the ``from'' person (i.e., the envelope sender of the mail). This address may also be used in the From: header if that header is missing during initial submission. The envelope sender address is used as the recipient for deliv- ery status notifications and may also appear in a Return-Path: header. -f should only be used by ``trusted'' users (normally root, daemon, and net- work) or if the person you are trying to become is the same as the person you are. Otherwise, an X- Authentication-Warning header will be added to the message. Of course, add the userid that formmail is running as to sendmail's list of trusted users, if you wish to suppress the warning header mentioned. 10-sec# cd /tmp 11-sec# cat test_message Subject: a test message From: root@localhost To: Charlie Root Date: about now test 1 2 3 12-sec# sendmail -f'toor@sec' root@localhost test_message 14-sec# tail -25 /var/mail/root Rebuilding whatis database: -- End of weekly output -- From [EMAIL PROTECTED] Sat Feb 15 22:33:30 2003 Return-Path: [EMAIL PROTECTED] Received: from sec.codefab.com (smmsp@localhost [127.0.0.1]) by sec.codefab.com (8.12.6/8.12.6) with ESMTP id h1G3XSwb028437 for [EMAIL PROTECTED]; Sat, 15 Feb 2003 22:33:28 -0500(EST) (envelope-from [EMAIL PROTECTED]) Received: (from root@localhost) by sec.codefab.com (8.12.6/8.12.6/Submit) id h1G3XSJd028436 for root@localhost; Sat, 15 Feb 2003 22:33:28 -0500 (EST) Message-Id: [EMAIL PROTECTED] Subject: a test message From: [EMAIL PROTECTED] To: [EMAIL PROTECTED], [EMAIL PROTECTED] Date: about now X-Spam-Status: No, hits=3.6 required=8.0 tests=INVALID_DATE,NO_REAL_NAME,SPAM_PHRASE_00_01 version=2.43 X-Spam-Level: *** test 1 2 3 -Chuck To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
