Reply for SendMail

[Harikrishna Babu]

Hi,

I've configured the Sendmail on HP-UX 11.0 - works fine. Now, I would like to accept the reply for the mails back to the HP-UX Server.

Can anyone shed some light to configure this?

Regards,
Hari

Sendmail should be already accepting incoming mail for local delivery. Mail addressed specifically for your server may be delivered by some agents.

You need to get your server setup in the DNS tables as a mail exchanger (MX record). You should also get your upsteam providers to act a mail exchanger for you.
Typically one or more servers in an organization accept
outside mail. To get an idea of how some organizations
set up mail delivery use the "host" command with the
"-t MX" to look at some of your favorite domains.

If you want outside mail delivered to your server then
your domain mail exchange should be set up to route
mail to your server.

You can test to see if your SendMail accepts mail from
outside servers set Netscape on a PC to use it as the SMTP server and send mail to a user on your server.
Send mail elsewhere to see if it is forwarding mail.

I wonder if you are referring to masquerading here? If you have configured sendmail to hide the hostname (DM in sendmail.cf) in the outgoing address (for example: "user@domain.com" instead of "user@host.domain.com") you need to have a route back to the originating user at that host.

I would suggest that you look in the knowledge base (or the internet) for descriptions of "mailertable" and "userdb".
