Question
Configuring Postfix to use my domain

I’ve got a postfix config that’s sending emails just fine, except that the sender address is root@lamp-512mb-lon1-01.localdomain, 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” xyz@hotmail.co.uk
Any help would be appreciated!

Hello. I had the same issue, and I found out… https://www.digitalocean.com/community/questions/system-has-configured-manage_etc_hosts-as-true
By the way, I’ve Ubuntu.
I solved it by adding to the file /etc/cloud/cloud.cfg
manage_etc_hosts: False
And editing /etc/hosts
After the “127.0.1.1” I added myhostname.swe just
Also, I had edited /etc/postfix/main.cf (myhostname= and myorigin=)
Then I restarted (server and) postfix
sudo systemctl restart postfix
@jtittle any other ideas?

The line in your configuration that looks like:
… is why you’re seeing that :-). That should be your actual hostname (mail.yourdomain.com) or your domain itself (yourdomain.com).
