Ubuntu – Postfix won’t forward email using virtual_alias_domains and virtual_alias_maps

Here is what i did:

• apt-get install postfix
• picked "internet mail"
• added a file "virtual" and appended a list with emails and emails (see below for sample)
• when changing postfix, i always updated the virtual db ( with command) and reloaded + restarted the postfix service
• example.com has a A-Record to the correct IP (hosting + Mailserver on the same server). (Also, Telnet connection doesn't give an error when connecting)

Example of the virtual file

 a_random_email@example.com my_email@gmail.com
 a_random_email_2@example.com my_email_2@gmail.com

Here's what i didn't do (and it's not required) i suppose:

• Did not create a ubuntu user per email (that's why i'm using virtual domains)

This is the contents of postconf -n

root@Host-Wordpress-01:~# postconf -n
alias_database = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
home_mailbox = mail/
inet_interfaces = all
inet_protocols = all
mailbox_size_limit = 0
mydestination = example.com, Host-Wordpress-01, localhost.localdomain, localhost
myhostname = example.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost =
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes
virtual_alias_domains = example.com
virtual_alias_maps = hash:/etc/postfix/virtual

I don't understand why, but i have one emailaddress that CAN mail to myselve (the forward = the sender mail). All other situations aren't working.

For example, when my virtual file contains:

a_random_email@example.com my_email@gmail.com

When i mail from my_email@gmail.com to a_random_email@example.com, then it gets into the inbox of my_email@gmail.com… Weird :s

There is no email in the postfix queue

I have already search through serverfault to find relevant questions, i haven't found any that solves my issue…

I'd like to solve this but an alternative for postfix ( if simple) is also accepted.. ( haven't found any though)
