Based on falko's Postfix + Mysql Tutorial for Centos 5.1 (http://www.howtoforge.com/virtual-users-and-domains-postfix-courier-mysql-centos5.1) I was having good progress up until I had to test the SMTP server, here is where the problem starts. When I try to connect to SMTP server it fails (not firewall) and I can't seem to figure it out Trying to connect to SMTP automatically results in a refused connection (not firewall). Code: [root@guinness postfix]# telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. [root@guinness postfix]# When I look at /var/log/maillog I get this: Code: [root@guinness postfix]# cat /var/log/maillog Dec 31 03:31:04 guinness postfix/smtpd[3483]: warning: xsasl_cyrus_server_get_mechanism_list: no applicable SASL mechanisms Dec 31 03:31:04 guinness postfix/smtpd[3483]: fatal: no SASL authentication mechanisms Dec 31 03:31:05 guinness postfix/master[14238]: warning: process /usr/libexec/postfix/smtpd pid 3483 exit status 1 Dec 31 03:31:05 guinness postfix/master[14238]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling [root@guinness postfix]# Here is my /usr/lib/sasl2/smtpd.conf file: Code: [root@guinness postfix]# cat /usr/lib/sasl2/smtpd.conf pwcheck_method: authdaemond log_level: 3 mech_list: PLAIN LOGIN authdaemond_path:/var/spool/authdaemon/socket [root@guinness postfix]# And finally here is my postfix /etc/postfix/main.cf contents: Code: [root@guinness postfix]# postconf -n 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 = guinness.tylerc.org, localhost, localhost.localdomain myhostname = guinness.tylerc.org mynetworks = 127.0.0.0/8 newaliases_path = /usr/bin/newaliases.postfix proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps 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 smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key smtpd_use_tls = yes transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf unknown_local_recipient_reject_code = 550 virtual_alias_domains = virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf virtual_create_maildirsize = yes virtual_gid_maps = static:5000 virtual_mailbox_base = /home/vmail virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf virtual_mailbox_limit_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_limit_maps.cf virtual_mailbox_limit_override = yes virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf virtual_maildir_limit_message = "The user you are trying to reach is over quota." virtual_overquota_bounce = yes virtual_uid_maps = static:5000 [root@guinness postfix]# -Tyler
