思科路由器配置
如果要使sendmail能和外部的邮件系统能够相互收发邮件首先要有mx交换记 录，其次，在sendmail服务器上还要做下列设置：思科路由器交换机
[root@localhost ~]# cat /etc/mail/access （设置为本地内网IP，192.168.0.0/24网段的IP进行中继）
# Check the /usr/share/doc/sendmail/README.cf file for a description
# of the format of this file. (search for access_db in that file)
# The /usr/share/doc/sendmail/README.cf is part of the sendmail-doc
# package.
#
# by default we allow relaying from localhost...

[root@localhost ~]# makemap hash /etc/mail/access.db < /etc/mail/access （生成数据库文件）
