摘要:关于550 Action not taken (in reply to end of DATA command)退信问题
之前关于hotmail和其它网站的550 Action not taken的相关日志已经给你了,现在给你我们的usa服务器产生的相关日志文件
usa的日志统计显示,以下的这句话今天到目前为止总共3506次,远远超过其它网站的100多次
(host 61.151.242.162[61.151.242.162] said: 550 Action not taken (in reply to end of DATA command))
 
一封usa邮件的日志如下:
Nov  8 15:08:40 usa amavis[7842]: (07842-09) Passed CLEAN {RelayedOpenRelay}, [49.70.232.126]:51667 [49.70.232.126] <nhtnvr@ylx.com> -> <hr@cbbc.org.cn>,  Hits: 5.304,  size: 42026, queued_as: DA72B6A7E4, 478 ms
邮件评分为5.304分,正常通过,因为usa的评分很宽松,是按照最原始的标准,但是接下来的这封邮件日志就是
Nov  8 15:08:42 usa postfix/smtp[7929]: DA72B6A7E4: to=<hr@cbbc.org.cn>, relay=61.151.242.162[61.151.242.162]:25,  status=bounced (host 61.151.242.162[61.151.242.162] said: 550 Action not taken (in reply to end of DATA command))
 
因为上海的postfix的垃圾邮件检查的评分标准非常严格,为什么说是因为垃圾邮件检查造成的Action not taken,
看上海的反垃圾邮件软件的相关参数的配置,第一列是主要参数和设定值,第二例是相关说明,第三列是原始设定的值
 
$sa_tag_level_deflt  = 1.0;                                       # add spam info headers if at, or above that level           2.0
$sa_tag2_level_deflt = 2.0;                                      # add 'spam detected' headers at that level                     6.2
$sa_kill_level_deflt = 2.2;                                         # triggers spam evasive actions (e.g. blocks mail)           6.9
$sa_dsn_cutoff_level = 2.6;                                     # spam level beyond which a DSN is not sent                  10
$sa_crediblefrom_dsn_cutoff_level = 8;                   # likewise, but for a likely valid From                                 18
# $sa_quarantine_cutoff_level = 25;                         # spam level beyond which quarantine is off
$penpals_bonus_score = 6;                                      # (no effect without a @storage_sql_dsn database)         8
$penpals_threshold_high = $sa_kill_level_deflt;       # don't waste time on hi spam
$bounce_killer_score = 30;                                        # spam score points to add for joe-jobbed bounces         100
$sa_mail_body_size_limit = 400*1024;                     # don't waste time on SA if mail is larger                            400*1024
$sa_local_tests_only = 0;                                           # only tests which do not require internet access?
 
看看第三行的说明里面就有action,美国的服务器的垃圾邮件配置的参数都似默认的,我没有更改过
记得曾经我们的大量中继客户发送邮件被我的postfix当做垃圾邮件退信,然后垃圾邮件评分被调整到很宽松
接着,网关客户收到的垃圾邮件太多了,然后评分调整到现在的严格,同一个时间,所有的客户都不进行垃圾邮件检查
由于我们不检查了客户发送的邮件是否为垃圾邮件,那么现在就是别人的服务器来检查我们发过去的是不是垃圾了
另外,不管是postfix还是smartermail,都会有误判垃圾邮件的事情,所以有了白名单
那么,同样道理,别人的邮件服务器也一样存在这样垃圾邮件误判的问题,包括hotmail
最终结论:Action not taken (in reply to end of DATA command) ,可能垃圾邮件,要么就是误判
