So in the postbox.com{in its dns} , I had made the MX bit as
192.168.0.20 <http://192.168.0.20>
I'd like to confirm that, but I get this:
$ host www.postbox.com
Host www.postbox.com not found: 2(SERVFAIL)
I think your zone has errors in it that you need to correct. It's
possible that this is the cause of the errors you're seeing.
I had add /etc/courier/hosteddomains the entry mail.postbox.com
hosteddomains should contain "postbox.com" if that is the domain that
for which you want to receive mail.
My login id must be [EMAIL PROTECTED]
... Exactly, you need "postbox.com" in the hosteddomains file.
What I understand is that when the mail is sending from
[EMAIL PROTECTED] to [EMAIL PROTECTED] courier will be searching for
the domain postbox.com which orginally have the ip 192.168.0.10, and
it fail to delever the mail since my actuall smtp is running on
mail.postbox.com which is running on 192.168.0.20
I don't think that's the case. The system sending mail will look up the
MX for the domain, and connect to 192.168.0.20. It will tell that
server that it has a message for [EMAIL PROTECTED] That server needs
to be configured to accept mail for postbox.com, and treat addresses as
hosteddomains. That means that you need to list postbox.com in both
esmtpacceptmailfor.dir and hosteddomains.
In this situation how could I make this kind of approch to work. Is
there any kind of aliasing possible. Please do correct me, actually I
am very new in mailserver/dns configurations.
Aliases should not be required.
