Using the Debian Sarge "Perfect Setup" when I got to the part to "telnet localhost 25" I get: Code: server1:~# telnet localhost 25 Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. Connection closed by foreign host. The second time I try it doesn't close and I can enter "ehlo localhost" and nothing happens. Here are the contents of my /etc/postfix/main.cf file: Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h myhostname = server1.strec.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname #mydestination = server1.strec.com, localhost.strec.com, , localhost relayhost = mynetworks = 127.0.0.0/8 mailbox_command = mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = nonanonymous broken_sasl_auth_clients = yes smptd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_tls_auth_only = no smtp_use_tls = yes smtpd_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom home_mailbox = Maildir/ virtual_maps = hash:/etc/postfix/virtusertable mydestination = /etc/postfix/local-host-names strec.com is the domain name I entered during the Debian setup and is not an internet domain. Should I try reinstalling postfix? If so, how do I go about that to make sure everything is removed completely?
