.dovecot 规则相应的扩展 参考 http://wiki2.dovecot.org/Pigeonhole/Sieve里面有说明 editheader 默认没有启用首先 90-sieve.conf

里面有说明 editheader 默认没有启用

首先 90-sieve.conf 里面要启用editheader

sieve_extensions = +editheader

# 邮件内容包含 Content-Disposition: attachment 时增加X-Has-Attach: yes否则no# 需要考虑的是邮件内容为明文则包含该内容时会命中该规则，如已有X-Has-Attach 也会再添加一次，可以判断修改规则require ["body","editheader"];    if body :raw :contains "Content-Disposition: attachment"    {        addheader "X-Has-Attach" "yes";    }    else    {        addheader "X-Has-Attach" "no";    }

另一个稍完整一点的，通过mime来判断

# 会先判断是否有X-Has-Attach，有则先删除再增加require [  "mime","editheader"];         if header :mime :param "filename" :matches ["Content-Type", "Content-Disposition"] ["*.*"]     {        if header :contains "X-Has-Attach" "yes"        {            deleteheader :index 1 "X-Has-Attach";            addheader "X-Has-Attach" "yes";        }        else        {            addheader "X-Has-Attach" "yes";        }          }     else     {        if header :contains "X-Has-Attach" "no"        {            deleteheader :index 1 "X-Has-Attach";            addheader "X-Has-Attach" "no";        }        else        {            addheader "X-Has-Attach" "no";        }     }

测试了下，通过不同的客户端的，会有误判的情况，根据上面文档改成下面的准确性要高一些，目前测试还未出现误判

require ["editheader", "mime"];        #if allof (     #    header :mime :anychild :contenttype "Content-Type" "application/octet-stream",    #    header :mime :anychild :contenttype "Content-Disposition" "attachment")     if header :mime :anychild :contenttype "Content-Disposition" "attachment"    {       addheader "X-Has-Attach" "yes";    }    else    {       addheader "X-Has-Attach" "no";    }
