The Problem
As root, I send an email to John.
mailx john@example.com
The maillog contains status bounced, unknown user john.
postfix/local to=john@example.com, relay=local, delay=0.04, delays=0.02/0.01/0/0.01, dsn=5.1.1, status=bounced unknown user: "john"
My Setup
On a clean install of CentOS 7, I install Postfix.
yum install postfix
In the /etc/postfix/main.cf file, I use domain example.com.
mydestination = example.com
In the /etc/postfix/main.cf file, I set users home mailbox to Maildir/, and there is no mailbox command.
home_mailbox = Maildir/
mailbox_command =
In the /etc/postfix/main.cf file, I remove the comment from local recipient maps, to query local user accounts.
local_recipient_maps = unix:passwd:byname $alias_maps
I create a new user, John.
useradd john
I update the aliases database.
newaliases
I restart Postfix.
systemctl restart postfix
I verify Postfix is running.
systemctl status postfix
. . . active running
John's account exists in /etc/passwd.
john:x:1002:1002::/home/john:/bin/bash
The postconf command shows that Unix can be used to query users. This should mean that local_recipient_map = Unix:passwd.byname can be used to query users.
]# postconf -m | grep unix
unix
I am not sure if this is the problem, but the following command produces no output.
postmap -q john@example.com unix:passwd.byname
My question should not be a duplicate of this similar question, as the solution provided in this similar post is to set mydestination to localhost localhost.$mydomain. When I do this, and then restart Postfix, I get the same exact error in the mail log, "bounced - unknown user john.doe". Also, in this other post, there is a much more developed Postfix setup, with mysql. My setup is very simple.

Did you issue thenewaliasescommand? ... Postfix aliases

Thank you. I forgot about thenewaliasescommand. I have issued thenewaliasescommand as root, restarted Postfix, send a new email to john.doe@example.com as root, and still the issue persists, where "bounced unknown user john.doe" appears in/var/log/maillog.

This may or may not be related to your problem, but dots are a bad idea in UNIX usernames. That's becausejohn.doeused to be interpreted as userjohn, groupdoe. Some utilities still do that to this day.

Thank you for the tip @SatÃ…Â Katsura. I have replacedjohn.doewithjohn, and have verified the issue persists. I have updated my post to showjohn.

It's hard to tell what's going on without seeing your entire config and full logs. Which is why debugging Postfix configurations almost never works on Unix & Linux. I really suggest using thepostfx-userslist instead.
