You will also have to specify the hosts and domains on your local network that your sendmail server should masquerade. If you have decided to masquerade all the hosts in your local network, you just need to set the masquerade_entire_domain feature, as in:

QR Code Drawer In .NET

If, instead, you want to masquerade particular hosts or your domain has several subdomains that you want masqueraded, you list them in the MASQUERADE_DOMAIN entry. You can list either particular hosts or entire domains. For example, given a local network with the localhosts turtle.mytrek.com and rabbit.mytrek.com you can list them with the MASQUERADE_DOMAIN to have them masqueraded. The domain they are masqueraded as is specified in the MASQUERADE_AS entry.

If you want to masquerade all the hosts in your local network, you can simply list your local network's domain name. Should your local network also support several subdomains, you can list those as well to masquerade them. For example, to masquerade all the hosts in the mybeach.com domain, you would use the following entry.

If you have a long list of domains or hosts, or you want to be able to easily change those that should be masqueraded, you can place them in a file to be read by Sendmail. Specify the file with the MASQUERADE_DOMAIN_FILE command:

Decoding EAN / UCC - 13 In Visual C#.NET

FEATURE(masquerade_entire_domain)dnl
A common configuration for a local network would specify the domain name in the MASQUERADE_AS entry and in the MASQUERADE_DOMAIN entry. Using the example myisp.com for the domain, the entries would look like this:
MASQUERADE_AS('mytrek.com')dnl FEATURE(masquerade_entire_domain)dnl
If you wanted to masquerade as an ISP's mail domain, you would use the ISP's domain in the MASQUERADE_AS entry as shown here.
MASQUERADE_AS('myisp.com')dnl MASQUERADE_DOMAIN('mytrek.com')dnl
You can use the EXPOSED_USER feature to override masquerading for certain users. The following example exposes the user root in turtle.mytrek.com, allowing mail to be addressed using the turtle hosts, as in admin@turtle.mytrek.com, instead of admin@mytrek.com:
EXPOSED_USER('root)dnl
When mail is received from the outside bearing just the address mytrek.com, your network needs to know what host to send it to. This is the host designated as the mail server for the mytrek.com network. This information is provided by a mail exchange record (MX) in your DNS configuration that will specify that mail sent to mytrek.com will be handled by the mail server-in this case, turtle.mytrek.com:
mytrek.com. IN MX 0 turtle.mytrek.com.
You further have to be sure that MX relaying is enabled with the relay_based_on_MX feature:
FEATURE(relay_based_on_MX)dnl
All messages will appear to originate from the mail server's host. For example, if your Sendmail mail server is running on turtle.mytrek.com, then mail sent from a localhost called rabbit.mytrek.com will appear to have been sent from turtle.mytrek.com. To further masquerade envelopes as well as headers, you add the masquerade_envelope feature:
FEATURE(masquerade_envelope)dnl
You can also masquerade recipient addresses, so that mail sent to users on your localhost will be sent instead to the masqueraded address. Use the allmasquerade feature to enable recipient masquerading:
FEATURE(allmasquerade)dnl
Configuring Mail Servers and Mail Clients
Sendmail can be used as either a mail server, handling mail for various hosts on a network, or as a mail client, managing mail for local users on a particular host. In a simple network configuration, you would have each host running Sendmail in a client configuration, and one host operating as a mail server, relaying mail for the network hosts. For a local network connected to the Internet, your localhosts would run Sendmail in a client configuration, and your gateway would run Sendmail in a server configuration (though the mail server would not have to necessarily run on the gateway). The mail server would relay messages from the local network hosts out to the Internet. The mail server could also be used to block unwanted access from outside hosts, such as those sending spam mail. A basic client or server Sendmail configuration involves just a few features in the /etc/mail/sendmail.mc file. The default Red Hat configuration listed in the previous section only allows use on a single host, managing messages between users on that host. To enable client and server use, you will need to make changes to the /etc/mail/sendmail.mc file.
