postfix中policyd的使用

 

邮件系统使用的是iredmail5.0

 

使用起来，一切正常，由于使用了灰名单机制，没有收到过垃圾邮件。可是有一个问题出现，就是一些重要的邮件也会延迟，这样使用起来有的不方便。

我测试了好长时间，现在延迟的问题基本解决了。

现在我把白名单的添加过程贴出来。

vi /etc/policyd.conf

#####################################################################
#                            WHITELISTING              (functional) #
#####################################################################
#
# whitelisting:                                       default: on
#
#   this enables whitelisting of ip/netblocks. this is needed
#   if you want to allow any of the whitelisting features.
#
#                                                     1=on  0=off
WHITELISTING=1

#
# whitelist null sender:                              default: off
#
#   null senders are normally used for bounce messages. many
#   viruses use null senders so its wise to leave this disabled.
#
#                                                     1=on  0=off
WHITELISTNULL=0

#
# whitelist sender address/domain
#
#   this allows you to do whitelisting based on envelope sender
#   address or envelope sender domain. a number of people have
#   been asking for this. please AVOID using this as spammers
#   forge senders and domains a lot.
#
#                                                     1=on  0=off
WHITELISTSENDER=1

#
# whitelist client dns name
#
#   this allows you whitelist clients that have proper resolving
#   records. for example, i could whitelist 'bulk.scd.yahoo.com'.
#   so any connections from n6a.bulk.scd.yahoo.com or
#   n6b.bulk.scd.yahoo.com would be whitelisted. this type of
#   whitelisting gives far greater power when it comes to
#   whitelisting ISPs or big companies which you know do not
#   house spammers. please note. this table must NOT have more
#   than 10 000 -> 15 000 entries.
#
#                                                     1=on  0=off
WHITELISTDNSNAME=1

#
# automatic whitelisting                              default: off
#
#   this allows whitelisting of remote networks who have sent
#   more than AUTO_WHITELIST_NUMBER of authenticated triplets.
#
#                                                     1=on  0=off
AUTO_WHITE_LISTING=1

#
# auto whitelist number:                              default: 500
#
#   how many succesfull triplets does it require before a
#   network is automatically whitelisted
#
AUTO_WHITELIST_NUMBER=10

保存，退出。

 

向数据库中添加信任的域，用户。

mysql> use policyd;

mysql> insert into whitelist_sender (_whitelist,_description) values( '@gmail.com','gmail.com');   添加整个邮件域，如果是单个邮件地址，则输入邮件地址。

mysql> quit
