Sendmail and Masquerading

[Erik van der Meulen <eme@ncm.nl>]

Dear all,

I have noticed a small oddity with my addressing in sendmail. All seemed to
work really well with pop clients connecting to my Debian 1.1 box, but if I
use elm or plain mail my From: line is not correct. I (think I) have set up
sendmail to masquerade as avondel.xs4all.nl. My .mc file looks like this:


        divert(0)
        VERSIONID(`@(#)sendmail.mc	8.7 (Linux) 3/5/96')
        OSTYPE(debian)dnl
        FEATURE(nocanonify)dnl
        FEATURE(masquerade_envelope)dnl
        FEATURE(use_cw_file)dnl
        FEATURE(use_ct_file)dnl
        FEATURE(nodns)dnl
        define(`confTO_QUEUEWARN', `1d')dnl
        MAILER(local)dnl
        MAILER(smtp)dnl
        Cwavondel.xs4all.nl
        MASQUERADE_AS(avondel.xs4all.nl)dnl
        ## Custom configurations below (will be preserved)
        MAILER(uucp)dnl
        define(`UUCP_MAX_SIZE', 0)
        define(`SMART_HOST', uucp-dom:xs4all)

And if I send mail from root using elm, the header comes out like:
        
        X-POP3-Rcpt: eme@nlauc01
        Return-Path: sun4nl!souterrain.avondel!root

        From: root <root@souterrain.avondel>
        Message-Id: <199609011203.OAA11142@souterrain.avondel>
        Subject: Meel van elm
        To: eme@ncm.nl
        Date: Sun, 1 Sep 1996 14:03:07 +0200 (MET DST)

        Content-Transfer-Encoding: 7bit


Both the From: line and the Return-Path: are incorrect. That is, my
linux-box is indeed called souterrain and my local domain is avondel, but I
would like to masquerade as avondel.xs4all.nl

Any hints are greatly appreciated!
