1：卸載sendmail

cd /usr/ports/mail/sendmail

make deinstall

make clean

2:安裝postfix

cd /usr/ports/mail/postfix

make config #開(kāi)啟pcre，SASL2，BDB etc..

make install clean

安裝時(shí)候會(huì)同時(shí)安裝cyrus-sasl2庫(kù)，選擇配置時(shí)候選上BDB等..

安裝時(shí)還會(huì)提示是否替換系統(tǒng)默認(rèn)的mail程序，此處替換，因?yàn)橐呀?jīng)卸載sendmail

Would you like to activate Postfix in /etc/mail/mailer.conf [n]? Y

3:如果沒(méi)有提示安裝cyrus-sasl2庫(kù)，則需要自己手動(dòng)安裝，配置同上圖

cd /usr/ports/security/cyrus-sasl2

make install clean

4.安裝cyrus-sasl2-saslauthd程序，選擇配置時(shí)候選上BDB

cd /usr/ports/security/cyrus-sasl2-saslauthd

make install clean

添加一個(gè)系統(tǒng)用戶 test，測(cè)試認(rèn)證是否正常

testsaslauthd -u test -p pasword 命令測(cè)試時(shí),失敗提示: 0:NO “authentication failed” 成功則提示0: OK “Success.”

安裝完成后加入啟動(dòng)項(xiàng)

ee /etc/rc.conf

加入

saslauthd_enable=”YES”
postfix_enable=”YES”

5.編輯/usr/local/etc/postfix/main.cf 最下面加入

#本機(jī)郵件服務(wù)器域名，在域名里做一下mx解析，指向本機(jī)的公網(wǎng)ip，避免被識(shí)別為垃圾
myorigin = mail3.me.com
#開(kāi)啟smtp
smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
#白名單ip，可以不用驗(yàn)證密碼
mynetworks = 168.100.189.0/28, 127.0.0.0/8
smtpd_recipient_restrictions = permit_mynetworks permit_inet_interfaces permit_sasl_authenticated permit_mx_backup reject_unauth_destination
smtpd_client_restrictions = permit_sasl_authenticated
smtpd_sasl_local_domain = $myhostname

6.打開(kāi)目錄 /usr/local/lib/sasl2/里面有個(gè)Sendmail.conf，重要！

cp Sendmail.conf smtpd.conf

生成/etc/aliases.db,運(yùn)行 重要！

newaliases
