i have created virtual e-mail domains and

vpop accounts to virtual e-mail domains.

DNS is configured.
|

A record and ip address are set.
|

virtual e-mail domains are identified through nslookup and telnet.

|

What kind of "virtual" e-mail domains did you create? What
|
|
MTA (mail transport agent) are you using? sendmail, qmail,
|
|
Postfix, Courier, exim? What POP daemon are you using?
|
|
You've set A (address) records up in DNS? What about your MX
|
|
records?
|
|
</BLOCKQUOTE>
|
|
<BLOCKQUOTE>
|
|
You've used nslookup (or dig) to confirm that your domains and
|
|
hostname records appear as you intended them. However, you haven't
|
|
explained to us what you did and how you <EM>think</EM> it's supposed to
|
|
work.

This example looks completely bogus. "webber" doesn't look like
|
|
an Internet domain at all.

Obviously you don't understand the problem well enough to
|
|
explain your expectations, give relevant excerpts from the config
|
|
files that are involved, and provide details about which packages
|
|
you are using. Either you don't understand enough to ask an
|
|
answerable question, or you're too lazy to do so. (I hope it's
|
|
the former).

|
|
No. The "step-by-step" procedure for creating domains and POP servers
|
|
are covered in a number of HOWTOs and involve a large number of
|
|
decisions that must be made based on an understanding of a very large
|
|
body of information about networking. Also those steps and processes
|
|
differ greatly based on which packages you select. The selection of
|
|
packages is also a complex issue which should be based on a clear
|
|
requirements analysis.

Your question amounts to a request for us to perform a rather involved
|
|
consulting project for you. You should hire a consultant to provide
|
|
these services. If your needs are for a non-profit or community
|
|
service project, then you should solicit some local expertise to help
|
|
you with the project.

I have recently set up something that sounds remarkably like
|
|
what you need here. I grabbed the Courier MTA and webmail
|
|
package from (<A HREF="http://www.courier-mta.org"
|
|
>http://www.courier-mta.org</A>) site and built
|
|
the MTA (esmtpd), POP and IMAP servers, and the SQwebmail
|
|
CGI gateway (MUA: mail user agent).
|
|
</BLOCKQUOTE>
|
|
<BLOCKQUOTE>
|
|
Actually, I'm still setting it up. Unfortunately I haven't
|
|
had time to write up the basic details and I certainly haven't
|
|
had time to play with its advanced features and to figure out
|
|
how to host virtual domains on it.
|
|
</BLOCKQUOTE>
|
|
<BLOCKQUOTE>
|
|
Maybe, in a month or two, I'll have enough experience with
|
|
Courier and enough time to write up a HOWTO. I might also work
|
|
on creating a suite of <A HREF="http://www.debian.org/">Debian</A> packages for (some of) them (since
|
|
Debian currently only support the Courier-IMAP daemon).

Sorry, but you need a whole lot more specialized help then we
|
|
can give. Please feel free to write up a <EM>detailed</EM> explanation
|
|
of what you're trying to do and how your trying to do it, and
|
|
we <EM>might</EM> offer some further suggestions. As for "the earliest"
|
|
please keep in mind that this is a volunteer effort. If you want
|
|
timely service, pay for it.
