All the postfix directories in that howto work, but I did not go with his 'use my main.cf' I studied it, using postconf and created a script containing: # postfix config file # uncomment for debugging if needed #postconf -e 'soft_bounce=yes' # postfix main postconf -e 'delay_warning_time = 4' # network settings postconf -e 'inet_interfaces = all' postconf -e 'mydomain = mailserver.domain.com' postconf -e 'myhostname = mail.mailserver.domain.com' postconf -e 'mynetworks = $config_directory/mynetworks' postconf -e 'relay_domains = proxy:mysql:/etc/postfix/mysql-relay_domains_maps.cf' # mail delivery postconf -e 'recipient_delimiter = +' # mappings postconf -e 'alias_maps = hash:/etc/aliases' postconf -e 'transport_maps = hash:/etc/postfix/transport' # virtual setup postconf -e 'virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_alias_maps.cf, regexp:/etc/postfix/virtual_regexp' postconf -e 'virtual_mailbox_base = /home/vmail' postconf -e 'virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains_maps.cf' postconf -e 'virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_maps.cf' postconf -e 'virtual_mailbox_limit_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_limit_maps.cf' postconf -e 'virtual_minimum_uid = 101' postconf -e 'virtual_uid_maps = static:101' postconf -e 'virtual_gid_maps = static:12' postconf -e 'virtual_transport = dovecot' postconf -e 'dovecot_destination_recipient_limit = 1' # authentication postconf -e 'smtpd_sasl_auth_enable = yes' # postconf -e 'smtpd_sasl_security_options = noanonymous' postconf -e 'smtpd_sasl_local_domain = $myhostname' postconf -e 'broken_sasl_auth_clients = yes' postconf -e 'smtpd_sasl_type = dovecot' postconf -e 'smtpd_sasl_path = private/auth' # tls config postconf -e 'smtp_use_tls = yes' postconf -e 'smtp_tls_note_starttls_offer = yes' postconf -e 'smtp_tls_session_cache_database = btree:$data_directory/smtp_tls_session_cache' postconf -e 'smtpd_use_tls = yes' postconf -e 'smtpd_tls_loglevel = 1' postconf -e 'smtpd_tls_received_header = yes' postconf -e 'smtpd_tls_security_level = may' postconf -e 'smtpd_tls_session_cache_database = btree:/var/lib/postfix/smtpd_scache' # Change mail.example.com.* to your host name postconf -e 'smtpd_tls_key_file = /etc/pki/tls/private/mailserver.domain.com.key' postconf -e 'smtpd_tls_cert_file = /etc/pki/tls/certs/mailserver.domain.com.crt' cat <<EOF>>main.cf || exit 1 # rules restrictions smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_recipient_domain # uncomment for realtime black list checks # ,reject_rbl_client zen.spamhaus.org # ,reject_rbl_client bl.spamcop.net # ,reject_rbl_client dnsbl.sorbs.net EOF postconf -e 'smtpd_helo_required = yes' postconf -e 'disable_vrfy_command = yes' postconf -e 'smtpd_data_restrictions = reject_unauth_pipelining' ============================================ that append above addresses that postconf cannot handle continues. You can replace it with a single line command; I like the multiline formatting. If you want more help, let's take it off list. I am at IETF in Orlando right now, and IEEE 802 next week, then Passover after that, so my posting speeds will vary.
