Postfix sends to FQDN Hostname instead of Domain Name
You need to put an alias for root
in the /etc/aliases
file like below, and then run newaliases
and it should work.
root: [email protected]
I have tested it and it works.
Finally got it working. These are the steps I did to resolve my trouble:
1) mydestination:
Since I had a send only mail server, I left mydestination
in main.cf
file empty as per the postfix man page. However, doing do ended up having the above behaviour were the local emails are sent with hostname appended which was getting bounced. Therefore I added $hostname
and localhost
as mydestination
in main.cf
like this:
mydestination = $myhostname, localhost
2) aliases:
Next, I added the email address for root user in /etc/aliases
like this:
root: [email protected]
3) newaliases:
Lastly, I rebuild aliases and reloaded postfix
sudo newaliases
sudo service postfix reload
What Fixed it:
Since aliases are used for local delivery only and I dont have local delivery (meaning $mydestination is empty), having the root email address in aliases didn't make any difference. Now after adding the $hostname
to my destination, any emails sent to a user which was getting appended with $hostname
is getting picked up as $mydestination
that is then referring to aliases
which ultimately tells postfix to deliver that email to another email address.
What I still dont understand is why the postfix was ignoring the $domainname
as myorigin
in the first place and kept adding hostname
suffix to user is still a mystery. However, the above method seem to be the solution when postfix is adamant to add hostname
to all mails addressed to the user directly.
Hope this helps!
