Postfix with no auth setup in Ubuntu?
It is already configured to accept authenticated users, users in your networks or known mail addresses (smtpd_recipient_restrictions
).
So your easiest fix is to add your internal network to the mynetworks
variable. Something like this should do what you want (assuming that 192.168.x.x
is your internal network). The /8
means that everything up to the first dot has to be the same and the /16
means that everything up to the second dot has to be equal to your definition.
mynetworks = 127.0.0.0/8 192.168.0.0/16

Now, postfix has been setup by auth. I want to remove user login with username and password. I want to make anonymous SMTP Mail server. What path should I change or what line should I remove ?
my main.cf is following
# See /usr/share/postfix/main.cf.dist for a commented, more complete version smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h myhostname = smtp.wpecho.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = smtp.wpecho.com, localhost relayhost = mynetworks = 127.0.0.0/8 mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_tls_auth_only = no #Use these on Postfix 2.2.x only #smtp_use_tls = yes #smtpd_use_tls = yes #For Postfix 2.3 or above use: smtp_tls_security_level = may smtpd_tls_security_level = may smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/ssl/private/smtpd.key smtpd_tls_cert_file = /etc/ssl/certs/smtpd.crt smtpd_tls_CAfile = /etc/ssl/certs/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom always_bcc = [email protected]

saturngod almost 14 yearsyes, I use one web app but they didn't setup for SMTP username and password. I knew the effect and add ip in mynetworks may be best way
