# SHOW SOFTWARE VERSION OR NOT
#
# The smtpd_banner parameter specifies the text that follows the 220
# code in the SMTP server's greeting banner. Some people like to see
# the mail version advertised. By default, Postfix shows no version.
#
# You MUST specify $myhostname at the start of the text. That is an
# RFC requirement. Postfix itself does not care.
#
#smtpd_banner = $myhostname ESMTP $mail_name
#smtpd_banner = $myhostname ESMTP $mail_name ($mail_version) ← 找到这一行,接此行添加如下行:
smtpd_banner = $myhostname ESMTP unknow ← 添加这一行,不显示SMTP服务器的相关信息
在配置文件的文尾,添加如下行:
smtpd_sasl_auth_enable = yes ← 服务器使用SMTP认证
smtpd_sasl_local_domain = $myhostname ← 指定SMTP认证的本地域名(主机名)
smtpd_sasl_security_options = noanonymous ← 不允许匿名的方式认证
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
message_size_limit = 15728640 ← 规定邮件最大尺寸为15MB]
我是按着这个配置出来的
[root@sample ~]# chgrp postfix /etc/sasldb2 ← 将数据库归属改为postfix,
[root@sample ~]# chmod 640 /etc/sasldb2 ← 将数据库属性改为640
