Hi all! Can anyone help me out with some Postfix problems.
I'm setting up an email server using Postfix and the ipop3 program
with Red Hat 9. I can send and receive mail on the local machine (to
anywhere, from anywhere), and other users on the local network can use
the SMTP to send to other users in the same domain. The problem is
that other users on the local network CANNOT send mail to other domains.
What error? please show the error log.
In other words, how do I allow users on the local network to use my
SMTP to send mail to other addresses outside of my server's domain
while still not having my server act as an open relay?
by specifying your network in the mynetworks parameter.
Background: I've already specified the following changes in the stock
/etc/postfix/main.cf:
mynetworks_style = subnet
Try to comment this out. And instead use mynetworks to explicitly define
your subnets.
mydestination = $myhostname, localhost.$mydomain localhost $mydomain
Is this the exact entry? commas are missing.
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
In /etc/postfix/master.cf I've only made this change:
smtp inet n - n - - smtpd
ok.
regards,
Kenneth
