mail reply to a virtual domain?

Chowroc · 12-17-2004, 06:37 AM

There are 2 domains: zouben.org and dm04.com, they can resolve names for each other, zouben.org has a MX mail.zouben.org(postfix), but dm04.com has none.

Now I have set dm04.com to be a virtual domain of the SMTP Server, I deliver mails from zouben.org to dm04.com, yes ,the mails can be stored to the mailbox I have assigned.

But I have a question: if someone mail as:
FROM: USER@dm04.com
TO: USER@dm02.org
dm02.org has its own mail server, but how can it kown dm04.org is a virtual domain of zouben.org and it should deliver mail to mail.zouben.org?

After that, I build a truly virtual domain: vdm.com, SMTP Server can also store mail to the right mailbox I assigned, but the same problem .

thanks.

if dm04.com has no MX record, I don't think it knows that. How is your DNS configured?

I mean: How does smtp.dm02.org kown to send mail to mail.zouben.org for :
RCPT TO: USER@dm04.com ?

my DNS:

Code:

zouben.org.
              1D IN NS        @
              1D IN A         127.0.0.1
              1D IN A         192.168.0.11
Chowroc       1D IN A         192.168.0.11
