标签: base64 content-type procmail

我试图让procmail解码base64编码的附件。首先,我遵循一个简单的方法,在这里找到:

http://www.linuxquestions.org/questions/linux-software-2/procmailrc-decode-data-from-base64-encoded-emails-trying-to-decode-with-uudeview-933670/

然而,似乎procmail无法找到匹配项:

procmail: [7459] Mon Aug 10 10:54:43 2015
procmail: Assigning "LOGFILE=/home/myself/procmail.log"
procmail: Opening "/home/myself/procmail.log"
procmail: Assigning "LOGABSTRACT=yes"
procmail: Assigning "LINEBUF=65535"
procmail: No match on "^Content-Type: *text/plain"
procmail: Locking "/home/myself/scratch/prc.out.lock"
procmail: Assigning "LASTFOLDER=/home/myself/scratch/prc.out"
procmail: Opening "/home/myself/scratch/prc.out"
procmail: Acquiring kernel-lock
procmail: Unlocking "/home/myself/scratch/prc.out.lock"
Subject: FMSG:219

我的〜/ .procmailrc非常简单:

SHELL=/bin/sh
PATH=/bin:/usr/bin/:/sbin:/usr/sbin:$PATH
MAILDIR=$HOME/scratch   # this is a symlink to a scratch disk
DEFAULT=$HOME/scratch/prc.out
VERBOSE=yes
LOGFILE=/home/myself/procmail.log
LOGABSTRACT=yes
LINEBUF=65535

        | $HOME/mmencode -u -b

        :0 Afhw
        | formail -I "Content-Transfer-Encoding: 8bit"
}

这是邮件文件的开头:

如果我尝试匹配“Content-Type:multipart / mixed”,我确实得到了匹配:

procmail: Match on "^Content-Type: multipart/mixed;"
procmail: No match on "^Content-Transfer-Encoding: *base64"

但不是以下那些...... :(

类似于尝试

procmail: No match on "^Content-Type: application/x-ole-envelope"

我错过了什么?

2 个答案:

答案 0 :(得分:0)

正则表达式中的消息 header 中没有匹配项。如果要在正文中找到匹配项(包括但不限于MIME正文部分标题),请使用B标记;但适当的MIME支持将比这复杂得多,并且几乎不可能单独使用Procmail。

您正在复制的配方非常专门用于规范化单部分text/plain消息,而不是多部分。

您的问题非常笼统,因此我只能从广义上提出替代方案。也许根据一些可能在Procmail中表达的正则表达式标准将消息传递给munpack之类的东西;但对于任何更复杂的东西,可能会使用专门的Python(或Perl或Ruby等)脚本。

我的procmailrc正在工作

VERBOSE=on
LOGFILE=$HOME/.procmail.log/procmail.`date +%Y%m%d`.log
LOGABSTRACT=yes

:0Wc:mailparser.lock
| /usr/bin/python /home/qq/mailparser.py > mailparser.log

:0
* ^content-Type:
{
    # backup the complete mail first..
    # you can leave out this part if you don't want a backup of the complete mail
    :0c:
        $HOME/fetchmail/mail_backup

    :0fw
    | uudeview -i +a +o -p $HOME/fetchmail/attachments -

}

当我尝试

* ^Content-Type: *text/plain

我没有比赛。
