Receiving mail for a "fake domain"

Receiving mail for a "fake domain"

Post by Chris Lewic » Tue, 07 Mar 1995 15:01:52



Hi All,
        I'd like to set up my site such that I can receive mail for a
"non-existant" domain.  I'm aware of the Cm tag in sendmail.cf, but the
domain has to be defined and aliased to your IP to be able to use that.  
I'd like to set it up like AOL or other folks are doing it.


I'd also like to be able to append the fake domain on all outgoing mail
as well.  

The sysadmin here said something about MX records, but frankly, I don't
have the time to research it myself.

Can anyone help me out here?

Thanks in advance.

Looks like a very existant domain to me...

You can create subdomains inside your domain, with their own
zones/nameservers, or just have MX records for them, but, of course, if
you want to get mail for a non-existant domain, you have to create it (set
up a nameserver and register it with sri-nic or whoever that is that
handles the top-level domain you want to be in).

1. Sendmail: mails rejected with "550-unrouteable mail domain "blade150.lafr.de""

mails sent from my Sun Blade 150 (Solaris 9) via sendmail are rejected
by the destination mail server with message shown above in the subject line.

My sendmail.mc file look like this:
divert(0)dnl

OSTYPE(`solaris8')dnl
DOMAIN(`solaris-generic')dnl
FEATURE(`allmasquerade')
MASQUERADE_AS(lafr.de)dnl
MAILER(`local')dnl
MAILER(`smtp')dnl

I put in the domain name "lafr.de". I thought this will change

But it seems that I am missing something else.

Who can help me ?
