postfix防止垃圾邮件配置

基础工作 

  本文将讨论怎样配置Postfix(2.x和1.x),在垃圾邮件进入服务器之前阻止它。不过,在将本文所讨论的方法运用到您的邮件服务器中之后,您应该检查您的邮件日志,确保合法的用户邮件不会被阻止。 

  您可以查看如下链接得到一些指导性的信息:

  Postfix 2.x 

  打开/etc/postfix/main.cf文件,在其中增加如下的几行(如果相关的配置存在,就替换之): 

  vi /etc/postfix/main.cf 

  [...] 

  smtpd_helo_required = yes 

  disable_vrfy_command = yes 

  strict_rfc821_envelopes = yes 

  invalid_hostname_reject_code = 554 

  multi_recipient_bounce_reject_code = 554 

  non_fqdn_reject_code = 554 

  relay_domains_reject_code = 554 

  unknown_address_reject_code = 554 

  unknown_client_reject_code = 554 

  unknown_hostname_reject_code = 554 

  unknown_local_recipient_reject_code = 554 

  unknown_relay_recipient_reject_code = 554 

  unknown_sender_reject_code = 554 

  unknown_virtual_alias_reject_code = 554 

  unknown_virtual_mailbox_reject_code = 554 

  unverified_recipient_reject_code = 554 

  unverified_sender_reject_code = 554 

  smtpd_recipient_restrictions = 

   reject_invalid_hostname, 

   reject_unknown_recipient_domain, 

   reject_unauth_pipelining, 

   permit_mynetworks, 

   permit_sasl_authenticated, 

   reject_unauth_destination, 

   reject_rbl_client multi.uribl.com, 

   reject_rbl_client dsn.rfc-ignorant.org, 

   reject_rbl_client dul.dnsbl.sorbs.net, 

   reject_rbl_client list.dsbl.org, 

   reject_rbl_client sbl-xbl.spamhaus.org, 

   reject_rbl_client bl.spamcop.net, 

   reject_rbl_client dnsbl.sorbs.net, 

   reject_rbl_client cbl.abuseat.org, 

   reject_rbl_client ix.dnsbl.manitu.net, 

   reject_rbl_client combined.rbl.msrbl.net, 

   reject_rbl_client rabl.nuclearelephant.com, 

   permit 

  [...] 

  然后重新启动Postfix: 

  /etc/init.d/postfix restart 

  Postfix 1.x 

  打开/etc/postfix/main.cf,并在其中加入如下几行(如果相关的配置已经存在就替换之): 

  vi /etc/postfix/main.cf 

  [...] 

  smtpd_helo_required = yes 

  disable_vrfy_command = yes 

  strict_rfc821_envelopes = yes 

  invalid_hostname_reject_code = 554 

  multi_recipient_bounce_reject_code = 554 

  non_fqdn_reject_code = 554 

  relay_domains_reject_code = 554 

  unknown_address_reject_code = 554 

  unknown_client_reject_code = 554 

  unknown_hostname_reject_code = 554 

  unknown_local_recipient_reject_code = 554 

  unknown_relay_recipient_reject_code = 554 

  unknown_sender_reject_code = 554 

  unknown_virtual_alias_reject_code = 554 

  unknown_virtual_mailbox_reject_code = 554 

  unverified_recipient_reject_code = 554 

  unverified_sender_reject_code = 554 

  maps_rbl_domains = 

   multi.uribl.com, 

   dsn.rfc-ignorant.org, 

   dul.dnsbl.sorbs.net, 

   list.dsbl.org, 

   sbl-xbl.spamhaus.org, 

   bl.spamcop.net, 

   dnsbl.sorbs.net, 

   cbl.abuseat.org, 

   ix.dnsbl.manitu.net, 

   combined.rbl.msrbl.net, 

   rabl.nuclearelephant.com 

  smtpd_recipient_restrictions = 

   permit_sasl_authenticated, 

   permit_mynetworks, 

   reject_invalid_hostname, 

   reject_non_fqdn_hostname, 

   reject_non_fqdn_sender, 

   reject_unknown_sender_domain, 

   reject_unknown_recipient_domain, 

   reject_maps_rbl, 

   check_relay_domains 

  [...] 

  然后重新启动Postfix: 

  /etc/init.d/postfix restart
