I've read the archives about using an .m4 file to setup sendmail to allow my unregistered domain to send/receive email via my ISP. There is still one thing I do not understand. The Masquerading and Relaying page at www.sendmail.org <http://www.sendmail.org>; reads as if I need to enable masquerading via MASQUERADE_AS(host.domain) first, before I can use MASQUERADE_DOMAIN(my.unregistered.domain) The issue for me is that I don't want my system to masquerade as anything. I only want the unregistered domain to masquerade as the "FreeBSD system" an be converted to the domain known to the ISP. Specifically: Out of the box, FreeBSD has always just worked regarding email/sendmail. Sending mail from user@mypc.ISP.com <mailto:user@mypc.ISP.com> (where 'mypc' is the name of the FreeBSD system, not a sub-domain) would always work. Conversely, from the 'net, I could always send mail to user@mypc.ISP.com <mailto:user@mypc.ISP.com> . There is a TCP connection to sendmail on mypc (I believe the ISP DNS instructs the sending system to try sending mail to mypc directly as the ISP does *not* have an MX record for my system; my cable ISP doesn't support other domains.) There is no need for this system to "look like" another domain. So I don't need to set MASQUERADE_AS(isp.com). Nor do I want to, the ISP would put all mail in one mailbox. I *do* want the other systems on my LAN, using the unregistered domain for email between them, to be able to send and receive mail to/from the ISP. For mail not local to the unregistered domain, I need the unregistered domain to become mypc.ISP.com (e.g. user@myfamily.com <mailto:user@myfamily.com> becomes user@mypc.ISP.com <mailto:user@mypc.ISP.com> for windows, user@pcname.myfamily.com <mailto:user@pcname.myfamily.com> becomes user@mypc.ISP.com <mailto:user@mypc.ISP.com> for other FreeBSD systems) However, using MASQUERADE_DOMAIN(my.unregistered.domain), according to how I read http://www.sendmail.org/m4/masquerading.html <http://www.sendmail.org/m4/masquerading.html>; only is used if MASQUERADE_AS is used. The only thing I can think of is to use MASQUERADE_AS(mypc.ISP.com) even though mail already uses this. Since this is very new to me, I'm looking for a bit of advice at this point. Am I even on the right track? Have I properly understood what I've read so far? Is there a better way of dealing with email? I am using FreeBSD 3.1-Release at the moment.
