邮件服务器Postfix+extmail+courier-imap配置
一.首先介绍安装环境：
 OS：centos5.4最小化安装，选择了组件 base，devlopment libraries development tools editors text-base internet 这几个组件，其他的一概不选。安装系统完毕，直接进行yum update -y &升级。
 在终端输入setup命令 选择firewall configuration 将security level 与SELinux 改为disabled，目的是为了避免在安装调试时产生不必要的麻烦，在系统安装完成后，可以自己去调试安全部分，在这里将不作详细介绍。

 二.组件选择说明：
 我们能用RPM 安装的，我们将采用rpm 安装，如果rpm没有的，我们将创建自己的rpm。部分软件简介：
 1、AMP －－－apache（web服务） 、mysql（数据库）、php（非必需） 的简称
 2、postfix －－mta 邮件系统核心
 3、courier-authlib－－一个为courier-imap，maildrop，sasl2 提供用户信息的后台进程序
 4、courier-imap －－提供pop3,pop3s,imap,imaps 服务的程序
 5、dspam clamd －－提供内容过滤 
 6、extmail －－一个著名的webmail程序
 7、extman －－与extmail集成的后台管理程序


 三：组件安装
 1、安装AMP
 [root@localhost ~]# yum -y install httpd httpd-devel mysql mysql-devel mysql-server php php-xml php-cli php-pdo php-mbstring php-mcrypt php-gd php-common php-devel php-mysql
 修改启动配置并启动
 [root@localhost ~]# chkconfig --level 345 mysqld on
 [root@localhost ~]# chkconfig --level 345 httpd on 
 [root@localhost ~]# service mysqld start
 [root@localhost ~]# service httpd start

 2.下载extman（http://www.extmail.org/cgi-bin/download.cgi）
 [root@localhost ~]# tar zxf extman-1.1.tar.gz 
 [root@localhost ~]# cd extman-1.1/docs/
 [root@localhost docs]# mysql -uroot <extmail.sql 
 [root@localhost docs]# mysql -uroot <init.sql

 3、RPM 简介
 下面我们将采用rpm 的方式安装软件
 /usr/src/redhat/SPEC spec 文件夹，通常是rpm文件夹
 /usr/src/redhat/RPMS 是生成rpm 的文件，下面还有i368,i486 等子文件夹，一般我们用i386 架构
 /usr/src/redhat/SOURCE 源文件文件夹
 为了安装时切换目录的方便，我们将目录存放到一个shell变量里。
 [root@localhost ~]# export RPMS=/usr/src/redhat/RPMS
 [root@localhost ~]# export SOURCE=/usr/src/redhat/SOURCES
 [root@localhost ~]# export SPEC=/usr/src/redhat/SPECS
 在下面安装过程中，大家要记住cd $RPMS 与cd /usr/src/redhat/RPMS 的目的是一样的，只是shell变量的替换。

 4、安装authlib （courier-authlib-0.63.0）
 A、安装依懒的包
 [root@localhost ~]# yum -y install postgresql-devel expect libtool-ltdl-devel
 [root@localhost ~]# wget http://prdownloads.sourceforge.net/courier/courier-authlib-0.63.0.tar.bz2
 [root@localhost ~]# tar xjf courier-authlib-0.63.0.tar.bz2 
 [root@localhost ~]# cd courier-authlib-0.63.0
 [root@localhost courier-authlib-0.63.0]# cp courier-authlib.spec $SPEC
 [root@localhost courier-authlib-0.63.0]# cd ..
 [root@localhost ~]# cp courier-authlib-0.63.0.tar.bz2 $SOURCE
 [root@localhost ~]# cd $SPEC
 [root@localhost SPECS]# rpmbuild -bb courier-authlib.spec （创建rpm文件）
 B、安装生成的rpm
 [root@localhost SPECS]# cd $RPMS/i386
 [root@localhost i386]# rpm -ivh courier-authlib-0.63.0-1.i386.rpm 
 [root@localhost i386]# rpm -ivh courier-authlib-devel-0.63.0-1.i386.rpm  
 [root@localhost i386]# rpm -ivh courier-authlib-mysql-0.63.0-1.i386.rpm  
 C、配置authlibdaemon
 [root@localhost i386]# cd /etc/authlib/
 [root@localhost authlib]# mv authdaemonrc authdaemonrc.bak
 [root@localhost authlib]# vim authdaemonrc
 输入下面的内容：
 authmodulelist="authmysql"
 authmodulelistorig="authmysql"
 daemons=10
 authdaemonvar=/var/spool/authdaemon
 DEBUG_LOGIN=2
 DEFAULTOPTIONS="wbnodsn=1"
 LOGGEROPTS=""
 D、配置authmysqlrc
 [root@localhost authlib]# mv authmysqlrc authmysqlrc.bak
 [root@localhost authlib]# vim authmysqlrc
 输入下面的内容：
 MYSQL_SERVER localhost
 MYSQL_USERNAME extmail
 MYSQL_PASSWORD extmail
 MYSQL_PORT 0
 MYSQL_SOCKET /var/lib/mysql/mysql.sock
 MYSQL_OPT 0
 MYSQL_DATABASE extmail

 MYSQL_SELECT_CLAUSE SELECT username,password,"",uidnumber,gidnumber,\
 CONCAT('/home/domains/',homedir), \
 CONCAT('/home/domains/',maildir), \
 quota, \
 name \
 FROM mailbox \
 WHERE username = '$(local_part)@$(domain)' 

 E、启动authlib

 [root@localhost ~]# service courier-authlib start
 Starting Courier authentication services: authdaemond
 [root@localhost ~]# chmod 777 /var/spool/authdaemon/

 5.安装courier-imap
 由于courier-imap 不能用root身份生成rpm那么我们新建一个普通用户，并创建一个rpm环境
 [root@localhost ~]# useradd yiyou 在这里添加自己的用户
 软件包依懒需要安装openldap-server，rpm创建完成后可以删除
 [root@localhost ~]# yum -y install openldap-servers
 [root@localhost ~]# su - yiyou 
 [yiyou@localhost ~]$ mkdir -p rpm/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
 [yiyou@localhost ~]$ vim ~/.rpmmacros
 输入内容：
 %_topdir /home/yiyou/rpm
 [yiyou@localhost ~]$ wget http://prdownloads.sourceforge.net/courier/courier-imap-4.7.0.tar.bz2
 [yiyou@localhost ~]$ cp courier-imap-4.7.0.tar.bz2 rpm/SOURCES/
 [yiyou@localhost ~]$ tar xjf courier-imap-4.7.0.tar.bz2 
 [yiyou@localhost ~]$ cd courier-imap-4.7.0
 [yiyou@localhost courier-imap-4.7.0]$ cp courier-imap.spec ../rpm/SPECS/
 [yiyou@localhost courier-imap-4.7.0]$ cd ../rpm/SPECS/
 编辑courier-imap.spec 将下面的内容：
 %if %suse_version
 BuildRequires: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel %([ %{suse_version} -gt 819 ] && echo /usr/include/fam.h)
 %else
 BuildRequires: rpm >= 4.0.2 sed /usr/include/fam.h openldap-devel openldap-servers
 %endif
 改为：将此处fam.h 去掉 此处好像没有openldap相关选项 2010-1-12
 %if %suse_version 在这里好像提示没有安装openldap-server yum install openldap* 还真没装
 BuildRequires: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel 
 %else
 BuildRequires: rpm >= 4.0.2 sed openldap-devel openldap-servers
 %endif
 创建rpm
 [yiyou@localhost SPECS]$ rpmbuild -bb courier-imap.spec 
 完成rpm后，输入exit退出当前用户。
 [root@localhost ~]# rpm -ivh /home/yiyou/rpm/RPMS/i386/courier-imap-4.7.0-1.i386.rpm
 [root@localhost ~]# service courier-imap start

 6.安装cyrus-sasl

 [root@localhost ~]# yum install -y cyrus-sasl-devel cyrus-sasl-plain cyrus-sasl cyrus-sasl-lib
 A.配置sasl2
 创建/usr/lib/sasl2/smtpd.conf 文件，输入下面的内容：
 pwcheck_method:authdaemond
 log_level:3
 mech_list:PLAIN LOGIN
 authdaemond_path:/var/spool/authdaemon/socket

 7、安装postfix 升级至2.6.5
 A、下载软件包
 [root@localhost i386]# cd
 [root@localhost ~]# wget http://ftp.wl0.org/official/2.6/SRPMS/postfix-2.6.5-1.src.rpm
 [root@localhost ~]# rpm -ivh postfix-2.6.5-1.src.rpm 
 [root@localhost ~]# cd $SPEC
 编辑postfix.spec 修改下面的选项
 %define distribution rhel-5.0
 %define with_mysql_redhat 1
 %define with_sasl 2
 %define with_vda 1
 %define with_pcre 1

 B、创建rpm

 [root@localhost SPECS]# rpmbuild -bb postfix.spec 
 [root@localhost RPMS]# cd $RPMS/i386
 [root@localhost i386]# rpm -ivh postfix-2.6.5-1.rhel5.i386.rpm 

 C、切换mta

 [root@localhost i386]# alternatives --config mta （选择2，postfix）
 [root@localhost i386]# rpm -e sendmail
 [root@localhost i386]# cd /usr/sbin/
 [root@localhost sbin]# mv sendmail sendmail.bak
 [root@localhost sbin]# newaliases
 [root@localhost sbin]# ln -s sendmail.postfix sendmail

 D、配置postfix

 [root@localhost ~]# cd /etc/postfix/
 [root@localhost postfix]# mv main.cf main.cf.bak
 [root@localhost postfix]# vim main.cf

 输入下面的内容：

 queue_directory = /var/spool/postfix
 command_directory = /usr/sbin
 daemon_directory = /usr/libexec/postfix
 data_directory = /var/lib/postfix
 mail_owner = postfix
 unknown_local_recipient_reject_code = 550
 debug_peer_level = 2
 debugger_command = 
 PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
 
 ddd $daemon_directory/$process_name $process_id & sleep 5
 sendmail_path = /usr/sbin/sendmail.postfix
 newaliases_path = /usr/bin/newaliases.postfix
 mailq_path = /usr/bin/mailq.postfix
 setgid_group = postdrop
 html_directory = /usr/share/doc/postfix-2.6.5-documentation/html
 manpage_directory = /usr/share/man
 sample_directory = /etc/postfix
 readme_directory = /usr/share/doc/postfix-2.6.5-documentation/readme
 alias_database = hash:/etc/postfix/aliases
 alias_maps = hash:/etc/postfix/aliases
 myhostname = mail.360book.com.cn(修改为自己的域名)
 mydomain = 360book.com.cn(修改为自己的域名)
 mydestination = $myhostname
 smtpd_banner = 360book.com.cn ESMTP Mail System(修改为自己的域名)
 message_size_limit = 14680064
 virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
 virtual_mailbox_base = /home/domains
 virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
 virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
 virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_limit_maps.cf
 virtual_transport = maildrop
 maildrop_destination_recipient_limit = 1

 #sasl
 smtpd_sasl_auth_enable = yes
 smtpd_sasl2_auth_enable = yes
 smtpd_sasl_security_options = noanonymous
 broken_sasl_auth_clients = yes
 smtpd_recipient_restrictions = 
 permit_mynetworks,
 
 permit_sasl_authenticated,
 reject_unauth_destination,
 reject_unauth_pipelining,
 reject_invalid_hostname
 dspam_destination_recipient_limit = 1
 复制extman/docs 目录的cf 文件到/etc/postfix
 [root@localhost postfix]# cp /root/extman-1.1/docs/mysql_virtual_* .
 因为配置文件的用户、密码与数据库时一样，所以不用修改。
 [root@localhost postfix]# service postfix start

 9、安装maildrop
 A、下载生成RPM

 [root@localhost postfix]# cd
 [root@localhost ~]# wget http://prdownloads.sourceforge.net/courier/maildrop-2.3.0.tar.bz2
 [root@localhost ~]# cp maildrop-2.3.0.tar.bz2 $SOURCE
 [root@localhost ~]# tar xjf maildrop-2.3.0.tar.bz2 
 [root@localhost ~]# cd maildrop-2.3.0
 [root@localhost maildrop-2.3.0]# cp maildrop.spec $SPEC
 [root@localhost maildrop-2.3.0]# cd $SPEC
 编辑maildrop.spec 把下面：
 BuildRequires: /usr/include/fam.h gdbm-devel pcre-devel
 改为：
 BuildRequires: gdbm-devel pcre-devel
 把下面：
 %configure --with-devel --enable-userdb --enable-maildirquota \
 --enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
 --enable-restrict-trusted=0 \
 --enable-sendmail=/usr/sbin/sendmail
 改为：
 %configure --with-devel --enable-userdb --enable-maildirquota \
 --enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
 --enable-restrict-trusted=0 --enable-sendmail=/usr/sbin/sendmail \
 --enable-authlib
 B、创建安装maildrop rpm
 [root@localhost SPECS]# yum -y install pcre-devel
 [root@localhost SPECS]# rpmbuild -bb maildrop.spec 
 [root@localhost SPECS]# cd $RPMS/i386
 [root@localhost i386]# rpm -ivh maildrop-2.3.0-1.i386.rpm 
 C、添加虚似用户及创建目录
 [root@localhost i386]# cd 在这里提示已经添加了用户 应该是安装postfix的时候创建的用户
 [root@localhost ~]# groupadd -g 1000 vgroup
 [root@localhost ~]# useradd -g 1000 -u 1000 -s /sbin/nologin -d /dev/null vuser
 编辑/etc/postfix/master.cf ，加入下面的内容：
 maildrop unix - n n - - pipe
 flags=DRhu user=vuser argv=/usr/bin/maildrop -d ${user}@${nexthop} ${recipient} ${user} ${extension} ${nexthop}
 D、创建邮件存储目录
 [root@localhost ~]# mkdir -p /home/domains/extmail.org/postmaster
 [root@localhost ~]# maildirmake /home/domains/extmail.org/postmaster/Maildir
 [root@localhost ~]# chown -R vuser:vgroup /home/domains/ 
 E、测试maildrop
 [root@localhost ~]# echo "test" | maildrop -V 10 -d postmaster@extmail.commaildrop: authlib: groupid=1000
 maildrop: authlib: userid=1000 maildrop: authlib:logname=postmaster@extmail.org,
 home=/home/domains/extmail.org/postmaster, mail=/home/data/domains/extmail.org/postmaster/Maildir/
 maildrop: Changing to /home/data/domains/extmail.org/postmaster
 Message start at 0 bytes, envelope sender=postmaster@extmail.org
 maildrop: Attempting .mailfilter
 maildrop: Delivery complete.
 出现上以信息说明authlib，maildrop 工作正常
 F、测试pop3
 [root@localhost ~]# telnet localhost 110
 Trying 127.0.0.1...
 Connected to localhost.localdomain (127.0.0.1).
 Escape character is '^]'.
 +OK Hello there.
 user postmaster@extmail.org
 +OK Password required.
 pass extmail
 +OK logged in.
 list
 +OK POP3 clients that break here, they violate STD53.
 1 6
 .
 retr 1
 +OK 6 octets follow.
 test
 .
 quit
 +OK Bye-bye.
 Connection closed by foreign host.

 G、测试postfix
 [root@localhost ~]# perl -MMIME::Base64 -e 'print encode_base64("postmaster\@extmail.org");'
 cG9zdG1hc3RlckBleHRtYWlsLm9yZw==
 [root@localhost ~]# perl -MMIME::Base64 -e 'print encode_base64("extmail");'
 ZXh0bWFpbA==
 [root@localhost ~]# service postfix restart （重启一下）
 [root@localhost ~]# telnet localhost 25
 Trying 127.0.0.1...
 Connected to localhost.localdomain (127.0.0.1).
 Escape character is '^]'.

这里会验证失败!下面会给出解决方案


 A、配置apache
 修改/etc/httpd/conf/httpd.conf，将下面的选项改为：
 User vuser
 Group vgroup
 在文件最后输入：Include /etc/httpd/conf.d/extmail.conf

 [root@localhost ~]# cd /etc/httpd/conf.d/
 [root@localhost conf.d]# vim extmail.conf
 输入下面的内容：
 Alias /extman/cgi/ /var/www/extsuite/extman/cgi/
 Alias /extman /var/www/extsuite/extman/html/
 <Location "/extman/cgi">
 SetHandler cgi-script
 Options +ExecCGI
 </Location>
 # config for ExtMail
 Alias /extmail/cgi/ /var/www/extsuite/extmail/cgi/
 Alias /extmail /var/www/extsuite/extmail/html/
 <Location "/extmail/cgi">
 SetHandler cgi-script
 Options +ExecCGI
 </Location>
 [root@localhost ~]# mkdir /var/www/extsuite
 [root@localhost ~]# tar zxf extmail-1.2.tar.gz 
 [root@localhost ~]# cp -r extmail-1.2 /var/www/extsuite/extmail
 [root@localhost ~]# cp -r extman-1.1 /var/www/extsuite/extman 
 B、配置extmail参数
 [root@localhost ~]# cd /var/www/extsuite/extmail/
 [root@localhost extmail]# cp webmail.cf.default webmail.cf
 修改webmail.cf 下面的选项
 SYS_SESS_DIR = /tmp/extmail
 SYS_MAILDIR_BASE = /home/domains
 SYS_MYSQL_USER = extmail
 SYS_MYSQL_PASS = extmail
 C、配置extman参数
 [root@localhost extmail]# cd /var/www/extsuite/extman/
 修改webman.cf 下面的选项：
 SYS_MAILDIR_BASE = /home/domains
 D、创建session 目录
 [root@localhost extman]# mkdir /tmp/{extman,extmail}
 [root@localhost extman]# chown vuser:vgroup /tmp/ext*

 E、配置后台日志分析工具
 [root@localhost addon]# cd /var/www/extsuite/extman/addon/
 [root@localhost addon]# cp -r mailgraph_ext /usr/local/
 将下面的内容加入/etc/rc.local
 /usr/local/mailgraph_ext/mailgraph-init start &
 /var/www/extsuite/extman/daemon/cmdserver --daemon &
 安装所依懒的软件包
 [root@localhost mailgraph_ext]# yum -y install rrdtool perl-rrdtool perl-GD perl-File-Tail perl-Unix-Syslog

 F、启动后台进程

 [root@localhost mailgraph_ext]# /usr/local/mailgraph_ext/mailgraph-init start
 Starting mail statistics grapher: mailgraph_ext

 G、访问extmail/extman
 打开浏览器，输入http://your_ip_address/extmail 注意：your_ip_address 为你实际的ip
 第一个测试用户为：postmaster 密码：extmail 域：extmail

 打开浏览器，输入http://your_ip_address/extman
 extman root 用户为：root@extmail.org 密码为：extmail*123*
 注意：进入系统后要修改密码及找回密码的提示问题、答案。

 11.安装dspam clamd
 yum install clamd dspam*
 进入mysql
 create database dspam;
 grant all on dspam.* to dspam@localhost identified by 'dspam';
 cd /usr/share/dspam/sql/mysql/
 修改mysql_objects-4.1.sql virtual_users.sql，在两个文件前添加 use dspam； 
 mysql -u dspam -p< mysql_objects-4.1.sql 
 mysql -u dspam -p< virtual_users.sql
 crontab -e
 0 0 * * * /usr/bin/mysql -u dspam -p'dspam' dspam < /usr/share/dspam/sql/mysql/purge-4.1.sql
 0 0 * * * /usr/bin/dspam_logrotate -a 30 -d /var/spool/dspam/data
 修改/etc/dspam/dspam.conf
 MySQLServer /var/lib/mysql/mysql.sock
 MySQLUser dspam
 MySQLPass dspam
 MySQLDb dspam
 MySQLCompress true
 MySQLUIDInSignature on
 ClamAVPort 3310 //开启clamd
 ClamAVHost 127.0.0.1
 ClamAVResponse spam
 ServerPID /var/run/dspam.pid
 ServerMode auto
 ServerParameters "--user dspam --deliver=innocent,spam"
 ServerDomainSocketPath "/tmp/dspam.sock"
 DeliveryHost 127.0.0.1
 DeliveryPort 10026
 DeliveryIdent localhost
 DeliveryProto SMTP
 ParseToHeaders on
 ChangeModeOnParse on
 ChangeUserOnParse full

 vi /etc/postfix/master.cf
 smtp inet n - n - - smtpd
 To：
 smtp inet n - n - - smtpd
 -o content_filter=lmtp:unix:/tmp/dspam.sock(-o 前面有三个空格)

 lmtp unix - - n - - lmtp

 127.0.0.1:10026 inet n - n - - smtpd
 -o content_filter=
 -o local_recipient_maps=
 -o relay_recipient_maps=
 -o smtpd_restriction_classes=
 -o smtpd_helo_restrictions=
 -o smtpd_sender_restrictions=
 -o smtpd_recipient_restrictions=permit_mynetworks,reject
 -o mynetworks=127.0.0.0/8
 -o strict_rfc821_envelopes=yes
 -o smtpd_error_sleep_time=0
 -o smtpd_soft_error_limit=1001
 -o smtpd_hard_error_limit=1000
 -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks
 配置dspam web 在/usr/share/dspam/webui/cgi-bin
 vi admins
 添加admin

 [root@localhost ~]#htpasswd -c .htpasswd admin
 xx
 xx
 /etc/init.d/dspam-webd start
 [root@localhost ~]#chkconfig --level 345 dspamd on
 [root@localhost ~]#chmod -R 777 /usr/share/dspam
 [root@localhost ~]#service dspamd start
 至此，整个postfix算是安装完毕。重启计算机，访问：http://your ip/extmail/就能直接访问了。

解决smtp验证问题May 9 20:42:49 mail postfix/smtpd[2536]: warning: unknown[ip]: SASL LOGIN authentication failed: authentication failure
现象：
 本地extmail能正常登陆并发送邮件出去。通过telnet登陆出现错误： 
1.  SASL LOGIN authentication failed: authentication failure
 
通过foxmail,php的smtp类登陆同样报此错。
分析：
查看验证配置文件：
 

   cat /usr/lib/sasl2/smtpd.conf 
    
  
 pwcheck_method: authdaemond 
  
 log_level: 3 
  
 mech_list: PLAIN LOGIN 
  
 authdaemond_path:/var/spool/authdaemon/socket 
  
且 /var/spool/authdaemon/socket 文件存在，权限为
 

   srwxrwxrwx 1 daemon daemon 0 Apr 30 15:44 /var/spool/authdaemon/socket 
 
 
也正常啊，难道本地的exmail不走验证机制？
 
1.  /usr/local/sbin/authtest -s login x@xok.la pass
 
这里的验证通过了。怪怪。。
仔细想了下这次邮局的配置，与以前大不同的是使用了不少RPM，减少编译过程。所以把怀疑对象定在了cyrus-sasl。
 
1.  rpm -qa|grep cyrus-sasl
 
发现没有cyrus-sasl，于是
 
1.  yum install cyrus-sasl
 
重新启动postfix,再次测试登陆。依然失败。
 

   saslauthd -v 
  
 authentication mechanisms: getpwent kerberos5 pam rimap shadow ldap 
  
支持的验证机制方法里怎么没有authdaemond。。看来RPM的默认是没有。。
解决：
 下载二进制cyrus-sasl包编译。 
 
  
 tar zvfx cyrus-sasl-2.1.22.tar.gz 
    
  
 cd cyrus-sasl-2.1.22 
  
 export LDFLAGS="-lpthread" 
  
 ./configure --with-mysql --enable-anon --enable-plain --enable-login --disable-krb4 --disable-otp --disable-cram --disable-digest --disable-gssapi --with-pam --with-authdaemond 
   
  

 make 
  
 make install 
  

 rm -rf /usr/lib/sasl 
  
 rm -rf /usr/lib/sasl2 
  
 ln -s /usr/local/lib/sasl2 /usr/lib/ 
  

 #为了让postfix能找到sasl,请运行如下命令: 
    
  

 echo "/usr/local/lib" >> /etc/ld.so.conf 
    
  
 ldconfig 
  

 cat > /usr/lib/sasl2/smtpd.conf <<EOT 
  
 pwcheck_method: authdaemond 
  
 log_level: 3 
  
 mech_list: PLAIN LOGIN 
  
 authdaemond_path:/var/spool/authdaemon/socket
