Hello,

Have you configured your hostname? If yes what are the errors shown in
/var/log/maillog and /var/log/messages?
Or seems to have some configuration missing. Paste the configuration file.

Hi infoshirish,

I solved the problem sending mails to users on the same PC but now unable to send mails from Internet to this PC.

Here is /etc/postfix/main.cf

#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

# TLS parameters
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_use_tls = yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${queue_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.satimis.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = ubuntu.satimis.com, satimis.com, localhost.satimis.com, localhost.localdomain, localhost
relayhost = 
mynetworks = 127.0.0.0/8, 192.168.1.0/24
mailbox_command = 
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
smtpd_sasl_local_domain = 
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
home_mailbox = Maildir/
virtual_alias_maps = hash:/etc/postfix/virtual
# Specify your NAT/proxy EXTERNAL address here.
proxy_interfaces = 1.2.3.4

$ hostname
ubuntu

$ hostname -f
ubuntu.satimis.com


I'm not sure whether it is the problem of this server OR mis-setting the DNS Control Panel on the Registrar's site. The domain is for testing use NOT for daily use. Previous it worked w/o problem.
