Hi, This is the first time ive posted on these forums but i have read them alot. I have also used alot of the How to guides. I setup my server following the installing A LAMP System With Fedora Core 6 (thanks falko!!!) Ive used this guide before and had everything up and running fine. I am using roudecube as my webmail client, and on all outgoing e-mails it says @localhost instead of the domain name. Eg [email protected]anlinksolutions.com I can still send e-mails but they all come through as [email protected]lhost I can change this in the preferences and its it will save it but its a hassel to log into each and every new e-mail account i create and fix it. postconf -n produces the following Code: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 html_directory = no inet_interfaces = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = /etc/postfix/local-host-names mynetworks = 127.0.0.0/8, 192.168.1.0/24 newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_tls_note_starttls_offer = yes smtp_use_tls = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_auth_only = no smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_loglevel = 1 smtpd_tls_session_cache_timeout = 3600s smtpd_use_tls = yes tls_random_source = dev:/dev/urandom Im rather new to linux, but i have looked around and cant really find much, i think its because i dont know what the actual problem is if you get my drift. Thanks in advance.
