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:
然而,似乎procmail无法找到匹配项:
procmail: [7459] Mon Aug 10 10:54:43 2015

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

:0 fbw
* ^Content-Transfer-Encoding: *base64
| $HOME/mmencode -u -b

| 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?
由于
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

当我尝试

我没有比赛。
