Debian – Postfix + Dovecot, send but not receive mail

I have followed the instructions in this tutorial. I can successfully sent emails but i cannot receive. Here is exactly what happens:

When i sent an email from my hotmail account if i do

# ls /home/vmail/example.com/info/mail/new/
1386353921.V918aI67830c7M607456.myvps

i see the mail, but if i login to squirrelmail i don't.

here is my /etc/postfix/main.cf

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

# 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 = myvps
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = myvps, localhost.localdomain, , localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

home_mailbox = Maildir/
virtual_mailbox_domains = /etc/postfix/vhosts
virtual_mailbox_base = /home/vmail
virtual_mailbox_maps = hash:/etc/postfix/vmaps
virtual_minimum_uid = 999
virtual_uid_maps = static:999
virtual_gid_maps = static:999

Here is the dig output:

# dig example.com MX +short
0 mail.example.com.

EDIT
And here is my /var/log/mail.log when i send an email to my vps email account:
