[英]Email Server; How to configure postfix to suit my needs? (Do I need SASL or/and TLS?)
我有一台Linux服务器,刚刚安装了postfix。
我没有对电子邮件服务器配置做更多的事情。
我的网站是一个分类网站,用户可以在其中放置广告,删除广告等。没有登录,也没有任何会员功能。
我唯一需要使用电子邮件的地方是这样的:
我的问题是,我应该如何配置Postfix?
我需要SASL和TLS吗? 我还需要知道什么?
顺便说一句,PHP用于邮寄...
这意味着后缀将仅在本地使用,因此为了安全起见,通过将防火墙配置为阻止端口25进入来防止外部用户与您的邮件联系。
编辑postfix'main.cf并设置以下内容,我认为这应该足以使您启动并运行。 如果其他设置也适用于您的情况,请确保也进行研究。
# The inet_interfaces parameter specifies the network interface
# addresses that this mail system receives mail on. By default,
# the software claims all active interfaces on the machine. The
# parameter also controls delivery of mail to user@[ip.address].
#
# See also the proxy_interfaces parameter, for network addresses that
# are forwarded to us via a proxy or network address translator.
#
# Note: you need to stop/start Postfix when this parameter changes.
#
#inet_interfaces = all
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost
inet_interfaces = localhost
# INTERNET HOST AND DOMAIN NAMES
#
# The myhostname parameter specifies the internet hostname of this
# mail system. The default is to use the fully-qualified domain name
# from gethostname(). $myhostname is used as a default value for many
# other configuration parameters.
#
#myhostname = host.domain.tld
#myhostname = virtual.domain.tld
# The mydomain parameter specifies the local internet domain name.
# The default is to use $myhostname minus the first component.
# $mydomain is used as a default value for many other configuration
# parameters.
#
#mydomain = domain.tld
# The relayhost parameter specifies the default host to send mail to
# when no entry is matched in the optional transport(5) table. When
# no relayhost is given, mail is routed directly to the destination.
#
# On an intranet, specify the organizational domain name. If your
# internal DNS uses no MX records, specify the name of the intranet
# gateway host instead.
#
# In the case of SMTP, specify a domain, host, host:port, [host]:port,
# [address] or [address]:port; the form [host] turns off MX lookups.
#
# If you're connected via UUCP, see also the default_transport parameter.
#
#relayhost = $mydomain
#relayhost = [gateway.my.domain]
#relayhost = [mailserver.isp.tld]
#relayhost = uucphost
#relayhost = [an.ip.add.ress]
