Dear Boa,

Answering your post yesterday, it seems that Mandrake block all the incoming/outgoing mail access from the ethernet IP 192.168.1.190, but it allow full access on localhost (127.0.0.1). This happens only in Mandrake distros.
To release this, enter the Webmin, access the menu :
Servers->PostFix Configuration->General options
find the "network interfaces receiving mail"
set it to "all interface" instead of localhost.

Hope this could solve the problem.

Hi all you guys,

I seeing that you have and haven't been able to telnet on port 25 for postfix. Basically this is necessary in order to receive e-mails.

If you can't telnet...you can fix it by editing the main.cf file and enable inet_interfaces = all

See an example of the main.cf file below:

# RECEIVING MAIL

# The inet_interfaces parameter specifies the network interface
# addresses that this mail system receives mail on. By default,
# the software claims all active interfaces on the machine. The
# parameter also controls delivery of mail to user@[ip.address].
#
# See also the proxy_interfaces parameter, for network addresses that
# are forwarded to us via a proxy or network address translator.
#
# Note: you need to stop/start Postfix when this parameter changes.
#
#inet_interfaces = localhost
inet_interfaces = all
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost


I hope this helps....

By the way, no need to install shorewall or something else, maybe Imap if you need it

Dear Phytorian,

I need some suggestion on controlling UCE ( SPAM ) from the mail server. I found two kind of authentication POP Before SMTP and SASL. I want to know their strengths and weakness'.

I want to replace my Exchange Server with Linux. Every internal Client will have to send password to authenticate when he/she send mail via SMTP. I want this feature also available in my upcoming Linux Mail server. Basicly I dont trust any mail client until they can supply the exact user name and password for sending mail.

Thanks in advance.
