Dear All, CentOS 5.2
Followed http://wiki.centos.org/HowTos/postfix and installed postfix dovecot system-switch-mail system-switch-mail-gnome Local delivery and local receipt works ok. Couldn't send email to external mail using 127.0.0.1 as smtp server. Now trying to make my computer a full fledged mail server. I am behind ADSL NAT got a dyndns address lal.homelinux.org. In adsl router, configured the above address, port forward tcp port 110 to 192.168.0.x ( x being ip address of my computer) can resolve lal.homelinux.org to ADSL WAN IP address. hostname of the computer set to lal.homelinux.org /etc/postfix/main.cf myhostname = lal.homelinux.org mydomain = homelinux.org myorigin = $mydomain inet_interfaces = all mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mynetworks = 192.168.0.0/24, 127.0.0.0/8 relay_domains = home_mailbox = Maildir/ nmaping lal.homelinux.org 22/tcp open ssh 25/tcp open smtp 110/tcp open pop3 111/tcp open rpcbind 143/tcp open imap 735/tcp open unknown 993/tcp open imaps 995/tcp open pop3s Can't get to send mail outside the system nor receive from external mail like gmail.com using smtp/pop3 as lal.homelinux.org Please help.
