cannot receive emails internally or externally
 
Hi,

I am new to Linux/Ubuntu OS. I have installed Ubuntu 10.04 with Postfix and Dovecot for IMAP.

I can send emails out to external account (e.g. yahoo) with no problem. The problem is I can not receive emails from external account such as yahoo. Even more strangely, I can not receive emails internally within my domain.

I was wondering if anyone would be kind to check my main.cf as follows

#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 = /usr/share/doc/postfix

# 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 = Ubuntu-MailServer.www.mycompany.com.au
myhostname = www.mycompany.com.au
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
# myorigin = /etc/mailname
myorigin = mycompany.com.au
# mydestination = www.mycompany.com.au, Ubuntu-MailServer.www.mycompany.com.au, localhost.www.mycompany.com.au, localhost
mydestination = www.mycompany.com.au, 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/
html_directory = /usr/share/doc/postfix/html

I have also found some warnings from mail.log as follows
Oct 22 02:30:02 Ubuntu-MailServer postfix/smtp[19995]: warning: host www.mycompany.com.au[152.56.77.100]:25 greeted me with my own hostname www.mycompany.com.au
Oct 22 02:30:02 Ubuntu-MailServer postfix/smtp[19995]: warning: host www.mycompany.com.au[152.56.77.100]:25 replied to HELO/EHLO with my own hostname www.mycompany.com.au
Oct 22 02:30:02 Ubuntu-MailServer postfix/smtp[19995]: 4CF6DC0542: to=<root@mycompany.com.au>, relay=www.mycompany.com.au[152.56.77.100]:25, delay=0.07, delays=0.03/0/0.04/0, dsn=5.4.6, status=bounced (mail for mycompany.com.au loops back to myself)

I wonder if anyone might be able to tell me what went wrong and how to work around this.

Any help would be greatly appreciated.

Thank you in advance

Please add mycompany.com.au to the mydestination line and restart Postfix.
