Configuring Postfix to use my domain
I've got a postfix config that's sending emails just fine, except that the sender address is email@example.com, which isn't using my domain.
The config file looks like the following:
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination myhostname = lamp-512mb-lon1-01.localdomain alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = $myhostname, skytracker.co, lamp-512mb-lon1-01.localdomain, localhost.localdomain, localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_protocols = all inet_interfaces = loopback-only
and /etc/mailname contains the domain that I would like to use to send emails from.
The command that I'm testing my email sending from is:
echo "This is the body of the email" | mail -s "This is the subject line" firstname.lastname@example.org
Any help would be appreciated!
