七、安装和配置maildrop
(
用于替代postfix的MDA功能,邮件投递代理,将收到的邮件转发到用户的邮箱目录)
1、安装
(1)
将courier-authlib的头文件及库文件链接至/usr目录(编译maildrop时会到此目录下找此些相关的文件):
#ln -sv /usr/local/courier-authlib/bin/courierauthconfig /usr/bin
#ln -sv /usr/local/courier-authlib/include/* /usr/include
(2)maildrop
需要pcre的支持,因此,接下来将首先安装pcre
#tar jxvf pcre-7.3.tar.bz2
#cd pcre-7.3
#./configure
#make
#make install
(3)创建maildrop所需的用户和组
#groupadd -g 1001 vmail
#useradd -g vmail -u 1001 -M -s /sbin/nologin vmail
(4)
开始安装maildrop
#tar jxvf maildrop-2.0.4.tar.bz2
#cd maildrop-2.0.4
# ./configure\
--enable-sendmail=/usr/sbin/sendmail\
--enable-trusted-users='root vmail'\
--enable-syslog=1 --enable-maildirquota\
--enable-maildrop-uid=1001\
--enable-maildrop-gid=1001\
--with-trashquota --with-dirsync
#make
#make install
(5)
检查安装结果,请确保有"Courier Authentication Library extension enabled."一句出现:
#maildrop -v
maildrop 2.0.4 Copyright 1998-2005 Double Precision, Inc.
GDBM extensions enabled.
Courier Authentication Library extension enabled.
Maildir quota extension enabled.

License. See COPYING for additional information.
2、新建其配置文件/etc/maildroprc文件,首先指定maildrop的日志记录位置:
#vi /etc/maildroprc
添加:
logfile "/var/log/maildrop.log"
#touch /var/log/maildrop.log
#chown vmail.vmail /var/log/maildrop.log
3、配置Postfix
(1)
编辑master.cf
# vi /etc/postfix/master.cf
启用如下两行
maildrop unix - n n - - pipe
flags=DRhu user=vmail argv=/usr/local/bin/maildrop -d ${recipient}
注意:定义transport的时候,即如上两行中的第二行,其参数行必须以空格开头,否则会出错.
(2)
编辑main.cf
#vi /etc/postfix/main.cf
virtual_transport = virtual
修改为:
virtual_transport = maildrop
将下面两项指定的UID和GID作相应的修改:
virtual_uid_maps = static:501
virtual_gid_maps = static:501
修改为:
virtual_uid_maps = static:1001
virtual_gid_maps = static:1001
4、编辑/usr/local/courier-authlib/etc/authlib/
authmysqlrc
#vi /usr/local/courier-authlib/etc/authlib/authmysqlrc
MYSQL_UID_FIELD '501'
MYSQL_GID_FIELD '501'
更改为:
MYSQL_UID_FIELD '1001'
MYSQL_GID_FIELD '1001'
注意:没有此处的修改,maildrop可能会报告 “signal 0x06”的错误报告
.
5、编辑/usr/local/apache/conf/httpd.conf,修改运行用户
如果启用了suexec的功能,则将虚拟主机中指定的
SuexecUserGroup postfix postfix
修改为:
SuexecUserGroup vmail vmail
如果没有使用上面的功能,则修改User和Group指令后的用户为vmail
将前文中的如下项
User postfix
Group postfix
修改为:
User vmail
Group vmail
6、将用户邮件所在的目录/var/mailbox和extman的临时目录/var/tmp/extman/的属主和属组指定为vmail
#chown -R vmail.vmail /var/mailbox
#chown -R vmail.vmail /var/tmp/extman/
7、重启postfix和apache,authlib
#/etc/init.d/courier-authlib restart
#/etc/init.d/httpd restart
#/usr/local/postfix/sbin/postfix stop
#/usr/local/postfix/sbin/postfix start
8 进行发信测试后,如果日志中的记录类同以下项,则安装成功
Sep 16 12:04:43 Ixor postfix/pipe[14266]: 46B491A5CB: to=<[email protected]>, relay=maildrop,
delay=2306, delays=2306/0.04/0/0.07, dsn=2.0.0, status=sent (delivered via maildrop service)
八、安装配置clamav-0.95.2.tar.gz(反病毒工具)
1、安装zlib-1.2.3
#tar zvxf zlib-1.2.3.tar.gz
#cd zlib-1.2.3
#./configure --prefix=/usr --shared
#make
#make test
#make install
2、安装clamav-0.95.2.tar.gz
(1)添加ClamAV运行所需的组和用户:
#groupadd clamav
#useradd -g clamav -s /sbin/nologin -M clamav
(2
)添加配合amavisd-new使用的用户amavis
#groupadd amavis
#useradd -g amavis -s /sbin/nologin -M amavis
(3)
开始安装clamav
#tar zxvf clamav-0.95.2.tar.gz
#cd clamav-0.95.2
#./configure --prefix=/usr/local/clamav\
--with-dbdir=/usr/local/clamav/share --sysconfdir=/etc/clamav
#make
#make install
