    Basically, I can send email to some places, but not others.
    When I send to my yahoo address, here are some of the headers:

    EHLO localhost.localdomain
    Received: from localhost.localdomain (localhost.localdomain []) by localhost.localdomain (Postfix) with ESMTP id DCE653885AD
    Received: (from [email protected]) by localhost.localdomain

    They shouldnt be like that, so how do I fix that. (I believe this is causing other problems).

    A bounce I get from another mail server: "554 <[email protected]>: Sender address rejected: Domain not found (in reply to RCPT TO command))

    Ive been working on fixing this all day! I fixed a few other problems to get to this stage, but I am stuck here! And my inexperience in linux (fedora) doesnt help.

    edit: I fixed the :EHLO localhost.localdomain to what it should be. (Was located in the file for postfix)
    The rest still say as above. The email i was trying to send finally started working, but should the rest of them be fixed up there?

    I get warning in my logs as well, such as:
    "Cannot load Certificate Authority Data" Warning TS Library problem....

    What is the output of the commands:



    hostname -f

    which linux distribution do you use?

    Does the contents of your hosts file like like this (except for the firs line)

    server1:/etc # vi hosts
    # hosts This file describes a number of hostname-to-address
    # mappings for the TCP/IP subsystem. It is mostly
    # used at boot time, when no name servers are running.
    # On small systems, this file can be used instead of a
    # "named" name server.
    # Syntax:
    # IP-Address Full-Qualified-Hostname Short-Hostname
    # localhost.localdomain localhost

    # special IPv6 addresses
    ::1 localhost ipv6-localhost ipv6-loopback

    fe00::0 ipv6-localnet

    ff00::0 ipv6-mcastprefix
    ff02::1 ipv6-allnodes
    ff02::2 ipv6-allrouters
    ff02::3 ipv6-allhosts server1

    Yea, basically (nothing about IPv6 though).

    look in the postfix config file and see if at the bottom of it your server name and domain are specified.... I think

    At the bottom of your hosts file where the ip's are listed ( what is the server name and domain name.

    What I would say is that it would be better to change the hostname and domain name of your system.

    actually this is the full text of my /etc/hosts

    #Do not remove the following line, or various programs
    # that require network functionality will fail. localhost.localdomain localhost

    How do I change the hostname and domain name?

    postconf -n | grep myhostname
    . Do you see a valid tld ? If not change it with
    postconf -e 'myhostname = xxx.your domain.tld'
    . And check the contents of /etc/mailname
