ubuntu postfix+SASL+smtp+pop3配置

1,安装postfix、SASL及smtp服务apt-get install postfix libsasl2 sasl2-bin libsasl2-modules libdb3-util procmail您将会被问一些问题:General type of configuration? <-- Internet SiteMail name? <-- server1.example.com2,配置postfixdpkg-reconfigure postfix您将再次被问一些问题:General type of configuration? <-- Internet SiteWhere should mail for root go <-- NONEMail name? <-- server1.example.comOther destinations to accept mail for? (blank for none) <-- server1.example.com, localhost.example.com, localhostForce synchronous updates on mail queue? <-- NoLocal networks? <-- 127.0.0.0/8Use procmail for local delivery? <-- YesMailbox size limit <-- 0Local address extension character? <-- +Internet protocols to use? <-- all3,配置postfix使它通过SASL实现smtp### Configure Postfix to do SMTP AUTH using SASL (saslauthd)postconf -e 'smtpd_sasl_local_domain ='postconf -e 'smtpd_sasl_auth_enable = yes'postconf -e 'smtpd_sasl_security_options = noanonymous'postconf -e 'broken_sasl_auth_clients = yes'postconf -e 'smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination'postconf -e 'inet_interfaces = all'echo 'pwcheck_method: saslauthd' >> /etc/postfix/sasl/smtpd.confecho 'mech_list: plain login' >> /etc/postfix/sasl/smtpd.conf生成用于加密和认证用的证书### Generate certificates to be used for TLS encryption and/or certificate Authenticationmkdir /etc/postfix/sslcd /etc/postfix/ssl/openssl genrsa -des3 -rand /etc/hosts -out smtpd.key 1024chmod 600 smtpd.keyopenssl req -new -key smtpd.key -out smtpd.csropenssl x509 -req -days 3650 -in smtpd.csr -signkey smtpd.key -out smtpd.crtopenssl rsa -in smtpd.key -out smtpd.key.unencryptedmv -f smtpd.key.unencrypted smtpd.keyopenssl req -new -x509 -extensions v3_ca -keyout cakey.pem -out cacert.pem -days 3650配置postfix，加密发送和接收的邮件### Configure Postfix to do TLS encryption for both incoming and outgoing mailpostconf -e 'smtpd_tls_auth_only = no'postconf -e 'smtp_use_tls = yes'postconf -e 'smtpd_use_tls = yes'postconf -e 'smtp_tls_note_starttls_offer = yes'postconf -e 'smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key'postconf -e 'smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt'postconf -e 'smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem'postconf -e 'smtpd_tls_loglevel = 1'postconf -e 'smtpd_tls_received_header = yes'postconf -e 'smtpd_tls_session_cache_timeout = 3600s'postconf -e 'tls_random_source = dev:/dev/urandom'postconf -e 'myhostname = mail.[MailServer].com4,重启postfix服务/etc/init.d/postfix restart5,做一些小的修改，以便于postfix可以通过saslauthd工作mkdir -p /var/spool/postfix/var/run/saslauthd6,编辑一下下面这个文件vim /etc/default/saslauthd# This needs to be uncommented before saslauthd will be run automaticallySTART=yesPWDIR="/var/spool/postfix/var/run/saslauthd"PARAMS="-m ${PWDIR} -r"# PIDFILE="${PWDIR}/saslauthd.pid"# You must specify the authentication mechanisms you wish to use.# This defaults to "pam" for PAM support, but may also include# "shadow" or "sasldb", like this:# MECHANISMS="pam shadow"MECHANISMS="shadow"7,这步很重要，因为我找了很多资料，这一步都没写对 ^_^vim /etc/init.d/saslauthd[...]PWDIR=/var/spool/postfix/var/run/saslauthdPIDFILE="/var/spool/postfix/var/run/${NAME}/saslauthd.pid"[...]8,配置一下sudo dpkg-statoverride --force --update --add root sasl 755 /var/spool/postfix/var/run/saslauthd9,重启saslauthd服务/etc/init.d/saslauthd start10,安装pop3服务apt-get install courier-authdaemon courier-base courier-imap courier-imap-ssl courier-pop courier-pop-ssl courier-ssl gamin libgamin0 libglib2.0-0回答他的问题Create directories for web-based administration ? <-- NoSSL certificate required <-- Ok做一些配置postconf -e 'home_mailbox = Maildir/'postconf -e 'mailbox_command ='/etc/init.d/postfix restart如果一切都正常的话，你现在可以用evolution之类的软件做测试了(ubuntu自带)
