一、首先安裝apache+mysql+php，
???????? 在本文檔中假設(shè)服務(wù)器的ip地址為172.16.27.23，域名為test.com，主機(jī)名為mail.test.com
?? 二、安裝courier-imap，courier-imap主要提供Pop3及IMAP服務(wù)。

??????1.ports安裝courier-imap

cd /usr/ports/mail/courier-imap
make install clean
????????選擇mysql

[X] AUTH_MYSQL?? MySQL support??????
???????? 2.在/etc/rc.conf 加入

courier_authdaemond_enable="YES"
courier_imap_pop3d_enable="YES"
courier_imap_imapd_enable="YES"
????????3.設(shè)置/usr/local/etc/authlib/authdaemonrc

cd /usr/local/etc/courier-imap
cp imapd.cnf.dist imapd.cnf
cp pop3d.cnf.dist pop3d.cnf
chmod -R??+x /var/run/authdaemond/

cd /usr/local/etc/authlib/
mv authdaemonrc authdaemonrc.bak
???? 編輯authdaemonrc文件，輸入如下內(nèi)容：

authmodulelist="authmysql"
authmodulelistorig="authmysql"
version="authdaemond.mysql"
daemons=5
authdaemover=/var/run/authdaemond
subsystem=mail
DEBUG_LOGIN=2
DEFAULTOPTIONS="wbnodsn=1"
???? 上面DEBUG_LOGIN=2 是為了調(diào)試方便，等系統(tǒng)完全測試完成，可改為 0，即不顯示調(diào)試信息。

/usr/local/etc/rc.d/courier-authdaemond start
????authdaemond 啟動完成后，檢查/var/run/authdaemond 下面是否產(chǎn)生socket 文件，因為認(rèn)證時是通過這個文件讀取密碼的。
??????
??????4.設(shè)置/usr/local/etc/authlib/authmysqlrc

cd /usr/local/etc/authlib/
mv authmysqlrc authmysqlrc.bak
?????? 創(chuàng)建authmysqlrc文件輸入以下內(nèi)容：

MYSQL_SERVER????????????localhost
MYSQL_USERNAME??????????extmail
MYSQL_PASSWORD??????????extmail
MYSQL_SOCKET????????????/tmp/mysql.sock
MYSQL_PORT??????????????3306
MYSQL_OPT?????????????? 0
MYSQL_DATABASE??????????extmail
MYSQL_USER_TABLE????????mailbox
MYSQL_CRYPT_PWFIELD???? password
MYSQL_UID_FIELD???????? 1000
MYSQL_GID_FIELD???????? 1000
MYSQL_LOGIN_FIELD?????? username
MYSQL_HOME_FIELD????????homedir
MYSQL_NAME_FIELD????????name
MYSQL_MAILDIR_FIELD???? maildir
MYSQL_QUOTA_FIELD?????? quota
MYSQL_SELECT_CLAUSE???? SELECT username,password,"",uidnumber,gidnumber,\
????????????????????????CONCAT('/services/data/domains/',homedir),?????? \
????????????????????????CONCAT('/services/data/domains/',maildir),??????\
????????????????????????quota,??????????????????????????????????????????\
????????????????????????name????????????????????????????????????????????\
????????????????????????FROM mailbox????????????????????????????????????\
????????????????????????WHERE username = '$(local_part)@$(domain)'
????要注意，我的郵件保存的目錄是/services/data/domains ，你可以跟據(jù)你的需要改為自己的目錄。用戶名和密碼是extmail 這個具體需要看extman 軟件包中的docs 目錄中的extmail.sql，很多人無法通上發(fā)信認(rèn)證，很可能以上面兩個文件配置有關(guān)。

????????三、安裝配置cyrus-sasl2

???? 1.ports安裝cyrus-sasl2

cd /usr/ports/security/cyrus-sasl2
make install WITH_AUTHDAEMON=yes
make clean
????2.創(chuàng)建 /usr/local/lib/sasl2/smtpd.conf 加入下面的內(nèi)容

pwcheck_method:authdaemond
log_level:3
mech_list:PLAIN LOGIN
authdaemond_path:/var/run/authdaemond/socket
????至此，認(rèn)證部分基本完成。

???????? 四、安裝配置Postfix
????????
????1.ports安裝postfix

cd /usr/ports/mail/postfix
make install clean
????2.編譯選項選擇

[X] VDA?????? VDA (Virtual Delivery Agent)
[X] MySQL???? MySQL map lookups (choose version with WITH_MYSQL_VER)
[X] TLS?????? SSL and TLS
[X] SASL2???? Cyrus SASLv2 (Simple Authentication and Security Layer)

安裝過程中有兩個提問，直接按回車，使用系統(tǒng)默認(rèn)的回答。

?? 3.配置postfix

echo postfix:root >> /etc/aliases
/usr/local/bin/newaliases
ln -s /usr/local/sbin/sendmail /usr/sbin/sendmail
???? 如果出現(xiàn)ln: /usr/sbin/sendmail: File exists 提示，把/usr/sbin/sendmail改名再鏈接。

????設(shè)置postfix 隨系統(tǒng)啟動，在/etc/rc.conf中添加如下內(nèi)容：

postfix_enable="YES"
sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"

??????創(chuàng)建/etc/periodic.conf 加入下面的內(nèi)容：

daily_clean_hoststat_enable="NO"
daily_status_mail_rejects_enable="NO"
daily_status_include_submit_mailq="NO"
daily_submit_queuerun="NO"

?? 配置/usr/local/etc/postfix/main.cf

cd /usr/local/etc/postfix/
mv main.cf main.cf.bak
????創(chuàng)建main.cf文件輸入如下內(nèi)容：

###################BASE##################
myhostname=mail.test.com
mydomain = test.com
mydestination = $myhostname
#mydestination =
local_recipient_maps =
command_directory = /usr/local/sbin
#local_transport = virtual

virtual_create_maildirsize = yes
virtual_mailbox_extended = yes

virtual_mailbox_limit_override = yes
virtual_maildir_limit_message = Sorry,the user's Maildir has overdrawn his diskspace quota ,please tray again later.
virtual_overquota_bounce = yes

##############SASL####################
smtpd_sasl_auth_enable = yes
smtpd_sasl2_auth_enable = yes
smtpd_sasl_security_options = noanonymous

readme_directory = no
sample_directory = /usr/local/etc/postfix
sendmail_path = /usr/local/sbin/sendmail
html_directory = no
setgid_group = maildrop
manpage_directory = /usr/local/man
daemon_directory = /usr/local/libexec/postfix
newaliases_path = /usr/local/bin/newaliases
mailq_path = /usr/local/bin/mailq
queue_directory = /var/spool/postfix
mail_owner = postfix
????以下幾個文件在extman軟件包的docs目錄下直接拷到/usr/local/etc/postfix下即可

mysql_virtual_alias_maps.cf
mysql_virtual_domains_maps.cf
mysql_virtual_limit_maps.cf
mysql_virtual_mailbox_maps.cf
mysql_virtual_sender_maps.cf

?? 至此postfix 基本設(shè)置完成，但還不能收發(fā)郵件。


?? 五、安裝配置maildrop

??????我們在設(shè)置郵件服務(wù)器時MTA 部分還是使用posfix 本身的帳戶進(jìn)行處理郵件，由于maildrop 不能和postfix 與同一用戶身份處理郵件，所以我們新開一個用戶用戶maildrop 處理。
pw groupadd vgroup -g 1000
pw useradd vuser -g 1000 -u 1000 -s /sbin/nologin -d /sbin/nologin -c "virtual mail user"

???? 1.ports安裝maildrop

cd /usr/ports/mail/maildrop
make install WITH_AUTHLIB=yes
???? 選擇

[X] AUTH_MYSQL?? MySQL support

make clean
????2.配置maildrop
?? 修改/usr/local/etc/postfix/master.cf ,把maildrop 原先已有的記錄注譯（即刪除舊記錄），加上下面的內(nèi)容

maildrop??unix??-?????? n?????? n?????? -?????? -?????? pipe
??flags=DRhu user=vuser argv=/usr/local/bin/maildrop -w 90 -d ${user}@${nexthop} ${recipient} ${user} ${extension} ${nexthop}
????3.設(shè)置郵件存儲目錄

mkdir -p /services/data/domains/test.com/test
chown -R 1000:1000 /services/data/domains/
chmod -R 700 /services/data
???? 確保data目錄為700權(quán)限以及所屬的用戶和組為vuser和vgroup

??至此，我們的郵件系統(tǒng)基礎(chǔ)部分已經(jīng)安裝完成了。重啟系統(tǒng)，開始進(jìn)行測試。


????六、安裝extmail和extman
????
??????1.解壓extmail和extman

tar xzvf extmail-1.2.tar.gz
tar xzvf extman-1.1.tar.gz
mkdir -p /services/extsuite
mv extman-1.1 /services/extsuite/extman
mv extmail-1.2 /services/extsuite/extmail
????2.修改httpd.conf文件，在末尾增加如下內(nèi)容：

<VirtualHost *:80>
????ServerName 172.16.27.23
????DocumentRoot /services/extsuite/extmail/html
????ScriptAlias /extmail/cgi /services/extsuite/extmail/cgi
????Alias /extmail /services/extsuite/extmail/html
????<Directory "/services/extsuite/extmail">
????Options ExecCGI
????AllowOverride None
????Order allow,deny
????Allow from all
????</Directory>
????#SuexecUserGroup postfix postfix
</VirtualHost>

#<VirtualHost *:80>
????DocumentRoot /services/extsuite/extman/html
????ScriptAlias /extman/cgi /services/extsuite/extman/cgi
????Alias /extman /services/extsuite/extman/html
????<Directory "/services/extsuite/extman">
#???? Options ExecCGI
????AllowOverride None
????Order allow,deny
????Allow from all
????</Directory>
#</VirtualHost>
????
????用戶和組修改為

User vuser
Group vgroup

?? 3.配置webman.cf和webmail.cf

????修改/services/extsuite/extman/webman.cf文件，參考內(nèi)容如下：
