Also, if your host goes by other hostnames and there are DNS records identifying your host by those names, you need to specify those names as well For example, your host could also be a web server to which mail could be directed A host turtlemytrekcom may also be identified as the website mytrekcom Both names would have to be listed in the mydestination parameter

If your system is a gateway for one or more local networks, you can specify them with the mynetworks parameter This allows your mail server to relay mail addressed to those networks Networks are specified using their IP addresses The relay_domains parameter lets you specify domain addresses of networks for which you can relay messages By default, this is set to mydestination:
mynetworks=19216800 relay_domains=$mydestination
Hosts within the local network connected to the Internet by a gateway need to know the identity of the relay host, the mail server You set this with the relayhost parameter Also, myorigin should be set to just mydomain If there is a DNS server identifying the gateway as the mail server, you can just set relayhost to the value of mydomain If not, then relayhost should be set to the specific hostname of the gateway/mail server If your local network is not running a DNS server, be sure to set disable_dns_lookups to yes
relay_host=$mydomain
Direct Connections
If your system is directly connected to the Internet and you use an ISP (Internet service provider) for receiving mail, you can configure Postfix as a null client to only send mail Set the relay_host parameter to just your own domain name Also, in the mastercf file, comment out the SMTP server and local delivery agent entries
relayhost = $mydomain

Masquerading
If your mail server is operating on a gateway for a local network and you want to hide the hosts in that network, you can opt to masquerade the localhost, letting it appear that all mail is coming from the domain in general, instead of a particular host To set this option, you use the masquerade_domains parameter In the following example, all mail sent by a localhost such as rabbitmytrekcom will be addressed as coming from mytrekcom Thus a message sent by the user chris@rabbitmytrekcom is sent out as coming from chris@mytrekcom:
masquerade_domains = $mydomain
Received mail is not masqueraded by default This allows Postfix to still deliver received mail to particular hosts If you want received mail to also be masqueraded, you have to add the envelope_recipients parameter to the list of values assigned to the masquerade_ class parameter In that case, Postfix will no longer be able to deliver received mail
Virtual Domains and Virtual Accounts
If your network has implemented virtual domains, you will need to set up a virtual domain table and then specify that table with the virtual_maps option Setting up a table is a simple matter of listing virtual names and their real addresses in a text file such as /etc/ postfix/virtual Then use the postmap command to create a Postfix table:
postmap /etc/postfix/virtual
In the maincf file, specify the table with the virtual_maps parameter Postfix will then use this table to look up virtual domains
