EMOS同一个域是不扫描的，我的没发现这个问题 [/quote]
同一个域不扫描是指dspam不扫描还是？
我的也有这个情况，本域发的邮件也到垃圾邮件箱里面了。 alias_database = hash:/etc/postfix/aliases

第二个方法:
修改@mynetworks.
编辑amavisd.conf
默认为:
@mynetworks = qw( 127.0.0.0/8 [::1] [FE80::]/10 [FEC0::]/10
10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 );
加入你要跳过过滤的IP网段
例如:
@mynetworks = qw( 127.0.0.0/8 [::1] [FE80::]/10 [FEC0::]/10
10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 222.45.26.0/24 );
同时修改MYNETS策略成如下
$policy_bank{'MYNETS'} = { # mail originating from @mynetworks
originating => 1, # is true in MYNETS by default, but let's make it explicit
os_fingerprint_method => undef, # don't query p0f for internal clients
bypass_spam_checks_maps => [1], # don't spam-check internal mail
bypass_banned_checks_maps => [1], # don't banned-check internal mail
bypass_header_checks_maps => [1], # don't header-check internal mail
};
保存后重启amaivsd
以后来自222.45.26.0/24的邮件都跳过检测.
同样会看到如下记录
amavis[15750]: (15750-11) Passed CLEAN, MYNETS LOCAL [222.45.26.132] [222.45.26.132] <[email]world@bendan.com.cn[/email]> -> <[email]duanmingde@yahoo.com.cn[/email]>, Message-ID: <E9E8D264BCF84E23AD210DC0E9A3C1CF@bendan13e0dfc8ed>, mail_id: VbR2kBqI-F1W, Hits: -, size: 11378, queued_as: E741F1D94001, 450 ms
这种方法也不是万金油,他也只能跳过来自@mynetworks中地址的邮件 EMOS本来就有这个配置:lol 按照上面方法都试了，同一个域的内部邮件还是被过滤，我的EMOS1.5, 同上。。。。。 这个问题还是没有解决吗?我也遇到同样的问题........................:( :( :(
dspam 收到邮件就自动关闭，求救
