配置postfix
由于一般web开发都有发送邮件的功能，django中也集成了该功能，所以用起来还是比较方便的，但是在生产环境，一般来说都是自己配置邮件服务器，其实可以想象，如果用户在你的网站注册了，然后收到的确认邮件来源是***@gmail.com等，可能就会觉得不正规。所以这里记录怎么粗糙的配置一下的postfix，然后在django中怎么使用。
第一步：先安装postfix, 我用的是ubuntu，直接apt-get就可以了
第二步：编辑/etc/postfix/main.cf,如下：
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.
myhostname = kier-laptop
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination =mydomain.com, kier-laptop, localhost.localdomain, localhost,
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = loopback-only
default_transport = error
relay_transport = error
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain = $myhostname
broken_sasl_auth_clients = yes
第三步：配置postfix的smtp认证：
先安装必要的包：
apt-get install libsasl2 sasl2-bin libsasl2-modules
修改/etc/default/saslauthd:
START=yes
PWDIR="/var/spool/postfix/var/run/saslauthd"
PARAMS="-m ${PWDIR} -r"
PIDFILE="${PWDIR}/saslauthd.pid"
MECHANISMS="pam"
OPTIONS="-c -m ${PWDIR}"
然后运行：
mkdir -p /var/spool/postfix/var/run/saslauthd echo 'pwcheck_method: saslauthd' >> /etc/postfix/sasl/smtpd.conf echo 'mech_list: plain login' >> /etc/postfix/sasl/smtpd.conf
第四步：adduser postfix sasl,设置用户postfix的密码为123456,后面会用到
第五步：chown postfix:sasl -R /var/spool/postfix
重启postfix, saslauthd
好了，现在在python命令行里面应该可以发邮件了，下面开始配置django工程里的setting文件：
EAMIL_HOST = 'localhost' DEFAULT_FROM_EMAIL = 'noreply@mydomain.com' EMAIL_HOST_USER = 'postfix' EMAIL_HOST_PASSWORD = '123456'重启apache，试试吧
