此处将原先的本机回环地址修改为侦听任意的IP地址

TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl

此处将前面dn1删除掉表示启用smtp认证,且认证的方式为本机认证

 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)

[root@localhost ~]# cat /etc/mail/local-host-names (设置本地域名)
