SUSE as an internal mail server


I have recently installed SUSE 10 and wanted to set it up as a mail server for our internal network. I computer only has one network card and I can't seem to get the firewall to open the proper port. When I type netstat -l it shows two rules for smtp both are the same.
tcp localhost:smtp *.* LISTEN
Should there not be a rule like tcp *:smtp *.* LISTEN ? I have enabled mail server on the external interface in Yast under firewall but it does not change any of the rules. Is there something in Postfix that needs to be changed or is the SUSE firewall not working properly because I only have one nic? I can telnet localhost 25 but I cannot telnet realip 25. Any help would be great!

Thanks in advance,
-Scott

yes, you need to tell postfix to listen on more then just localhost.

edit your main.cf, you most likely have something like this

Code:
#inet_interfaces = all
inet_interfaces = localhost
Switch the line thats commented, the do postfix reload and you should be set.

I had done what you suggested and it didn't seem to help but then I uncommented the mynetworks = and added my network range and everything seems to be working now. Thanks for your help though. The SUSE postfix config file is a little wierd with a lot of the config at the very end of the file. Here was my working main.cf file. Hope this might help if anyone else has problems.

queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/lib/postfix
mail_owner = postfix
unknown_local_recipient_reject_code = 550

xxgdb $daemon_directory/$process_name $process_id & sleep 5

masquerade_exceptions = root
masquerade_classes = envelope_sender, header_sender, header_recipient
myhostname = mail.example.com
mydomain = example.com
program_directory = /usr/lib/postfix
inet_interfaces = all
masquerade_domains =
mydestination = $myhostname, $mydomain, localhost.$mydomain
