Localmail missing for root

I have a running installation of Postfix and it's working locally. However, I find some strange issues.

If I run this as root:

echo "mail body" | mail -s "test mail" root

I expect to have mail as root user. However, If I run "mail", the system says:

No mail for root

I haven't any directory named Maildir under root folder.

/var/mail/root file is also empty.

If I do the same with another user as recipient, I find the mail under its Maildir/new directory.

¿What's going on?


Can you share all the maillogs of that specific mail which you sent to user root.

"alberto" is the user I am logged in as. But I am in an elevated prompt ("sudo su"), so I expect to be from root to root...
Isn't that from root to your alberto user that was being delivered to Maildir of that user and from root to alberto or root to root the mail not arriving in the Maildir of the root user? Also what distro are you running, Debian? Can you share your full configuration, so main.cf?

I'm running Debian9.

Additional info: I am running the mail command as "alberto", but with elevated privileges (sudo su - so I am root). ¿Can this have something to do?

No that shouldn't be a problem. Can you share your postfix configuration, so main.cf?

Sure, here you go:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.
compatibility_level = 2

home_mailbox = Maildir/

# TLS parameters

You configuration is correct, and worked because when I copy it to my test system I receive mails in Maildir format for both normal users and the root user. I would enable debug logging for postfix and then try again this way you will see more information in the syslog of what exactly postfix is doing.
