Postfix not receiving mail

Question

I setup my Virtualmin using the manual installation because I'm on Ubuntu 3.14 and the automatic install does not support this version.

Because of this now I have problems. Everything works except Postfix.

Here is my postconf -n:

ubuntu@web01:~$ postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
home_mailbox = Maildir/
mailbox_size_limit = 0
mydestination = web01.redacted.net, localhost, localhost.localdomain, localhost
myhostname = web01.redacted.net
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_recipient_restrictions = permit_inet_interfaces
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes
virtual_alias_maps = hash:/etc/postfix/virtual

The error I get in the mail.log is:

Mar 22 08:17:49 web01 postfix/smtpd[27725]: connect from nk11p04mm-asmtpout002.mac.com[17.158.236.237]

And this is the /etc/postfix/virtual:

redacted.co redacted.co
hostmaster@redacted.co  redactedName@redacted.co

Here is the /etc/aliases:

# See man 5 aliases for format
postmaster:    root

Answer 1

The problem was that the initial user in our case redactedName was not found. To solve this problem the user was manually added as per:

redacted.co redacted.co
hostmaster@redacted.co  redactedName@redacted.co
redactedName@redacted.co  redactedName

This fixed the problem.

I hope someone else finds this useful. It took a lot of debugging and looking at logs to finally understand what the error message was telling me was in fact the error itself. Basically the redactedName@redacted.co was not being redirected to any user.
