I am trying to setup a single server to send out email from a single domain but I'm having trouble identifying the correct values for these Postfix settings.
mydomain = example.com myhostname = example.com myorigin = $mydomain mydestination = $example, localhost.$example, localhost relayhost = mynetworks = 127.0.0.0/8 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all
Can someone can explain them so I know what I should be setting them to?
$mydomain appear to be added at runtime by the script. This seems to work (emails come from firstname.lastname@example.org) but I am weary of using values for parameters I don't understand.
