Linux – Setting up a forwarding-only email server

All I want to do is install postfix, and forward emails. I don't need anything to stay on my server. This is giving me hell. I tried the best I could, but postfix is denying all relays.

What I want is this. Say my server is at example.com. I want this:

Email forwarding:

user1@example.com -> user1@gmail.com
user2@example.com -> user2@yahoo.com
user3@example.com -> user3@hotmail.com

All I need is a forwarding box that redirects emails coming to it. Since there's obviously something wrong with my configuration, I could really just use an example main.cf for my purpose, and I'll be on my way.

Edit: Logs

The strange thing is the logs don't give me any errors.

main.cf:

mreiley@Omega-14:/var/log$ cat /etc/postfix/main.cf
# 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 (Ubuntu)
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

# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = omega-14.omegadev.org
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = omega-14.omegadev.org, localhost.omegadev.org, localhost
relayhost = 
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

virtual_alias_domains = omegadev.org monovec.com ifmovement.org
virtual_alias_maps = hash:/etc/postfix/virtual

mreiley@Omega-14:/var/log$ 

virtual forwards file:

mreiley@Omega-14:/var/log$ cat /etc/postfix/virtual
[EXPUNGED]@omegadev.org blahboybang@gmail.com
mreiley@omegadev.org blahboybang@gmail.com

mreiley@Omega-14:/var/log$ 

Then I send an email from gmail to test the configuration. This is what mail.log shows:

Jul 16 16:00:32 Omega-14 postfix/smtpd[4282]: connect from mail-px0-f179.google.com[209.85.212.179]

Jul 16 16:00:33 Omega-14 postfix/qmgr[4274]: 72784483A: removed

The log claims that the delivery was a complete success, but the email never shows up in my inbox or spam folder.

However, if I use telnet, I get a different story.

mreiley@Omega-14:/var/log$ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

250 2.1.0 Ok
rcpt to:blahboybang@gmail.com

Update! It would seem that GOOGLE ITSELF is blocking me. Emails sent to other providers go through, but when sent to gmail they don't even hit spam.
