6.1.5.Mail服务配置

mail服务的ip地址 vi /etc/sysconfig/network-scripts/ifcfg-eth0

mail服务的Dns vi /etc/resolv.conf

2.1 rpm –ivh 安装mail服务所需软件包 iptables 关闭防火墙 2.1.1 删除冲突软件,sendmail，需要执行: rpm -e --nodeps sendmail 安装postfix

rpm -ivh --nodeps RPMS/postfix-2.5.1-2ext.i386.rpm 简化postfix配置:

postconf -n > /etc/postfix/main2.cf

mv /etc/postfix/main.cf /etc/postfix/main.cf.old mv /etc/postfix/main2.cf /etc/postfix/main.cf 2.1.2再编辑main.cf： vi /etc/postfix/main.cf

增加如下内容： # hostname

mynetworks = 127.0.0.1

myhostname = mail.extmail.org

mydestination = $mynetworks $myhostname

# banner

mail_name = Postfix - by extmail.org

smtpd_banner = $myhostname ESMTP $mail_name

# response immediately

23

smtpd_error_sleep_time = 0s

unknown_local_recipient_reject_code = 450

# extmail config here

virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf

virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf virtual_transport = maildrop:

编辑mysql_virtual_alias_maps.cf

vi /etc/postfix/mysql_virtual_alias_maps.cf

内容如下： user = extmail

password = extmail hosts = localhost dbname = extmail table = alias

select_field = goto where_field = address

编辑mysql_virtual_domains_maps.cf

vi /etc/postfix/mysql_virtual_domains_maps.cf

内容如下： user = extmail

password = extmail hosts = localhost dbname = extmail table = domain

select_field = description where_field = domain

#additional_conditions = and backupmx ='0' and active ='1' 编辑mysql_virtual_mailbox_maps.cf

vi /etc/postfix/mysql_virtual_mailbox_maps.cf 内容如下： user = extmail

password = extmail hosts = localhost dbname = extmail table = mailbox

select_field = maildir where_field = username

#additional_conditions = and active = '1' 2.1.3

配置Courier-Authlib
