fdm - 嵌套操作

我正在尝试将来自票证系统的传入邮件分类到包含票号的邮件目录中。

发件人是：[email protected]

主题始终包含：RequestID: <numbers>

所以我尝试使用以下规则集：

match "^From:.*ticketsys@test\.de"             in headers {
   match "^Subject:.*RequestID:[  \t]*([0-9]*)" action tag "ticketno" value "%1" continue
    match matched action "ticket"
    match unmatched action keep
}

行动票看起来像这样：

action "ticket"        maildir  "%h/Mails/work/INBOX.Ticket-%[ticketno]"

它匹配，但新创建的文件夹以减号 ( Mails/work/INBOX.Ticket-) 结尾，就好像标记不成功一样。

以下是来自的日志fdm -kvvvv fetch：

票号未写入邮件目录。

更新到最新的 fdm 版本以确保包含所有修复

如何将标签写入邮件目录名称？

更新3：

主题行如下所示：

Subject: =?iso-8859-1?Q?Empfangsbest=E4tigung_f=FCr_Service?=
        =?iso-8859-1?Q?_Request_mit_der_Service_RequestID:?=
        =?iso-8859-1?Q?_1710000261_/__Domain:.test.de?=
        =?iso-8859-1?Q?_Subdmonains_f=FCr_Staging_Zwecke?=

答案1

似乎fdm没有进行 MIME 标头解码，因此当邮件标头被编码时，例如 as =?iso-8859-1?Q?...，您必须在正则表达式中明确考虑这一点。请注意，fdm 会在正则表达式阶段将多行标题连接到一行中以帮助您。

因此，如果您可以保证邮件的发件人始终使用完全相同的标头编码，您可以将正则表达式替换为类似的内容

match "^Subject:.*RequestID:.*\?Q\?_([0-9]*)" action tag "ticketno" value "%1" continue

这样您就可以跳过编码标头。然而，一个更干净的解决方案是引入一些 perl 代码（或类似的代码）将标头解码为 uft8，然后与原始正则表达式匹配。创建一个文件，例如/tmp/decodesubject，包含以下内容：

#!/usr/bin/perl
use open qw/:std :encoding(utf-8)/;
use Mail::Header; # perl-MailTools
use Encode;
my $head = new Mail::Header \*STDIN, FoldLength=>999;
my $subject = $head->get('Subject');
$subject = Encode::decode('MIME-Header', $subject); # -> utf8
print "Subject: $subject";

并使其可执行chmod +x /tmp/decodesubject。您可能需要安装诸如perl-MIME-tools或 之类的软件包libmime-tools-perl才能获取这些Mail::Header功能。该脚本读取标准输入上的邮件并仅打印解码后的主题标头。要从配置文件中调用它，请将上面的match行替换为

match pipe "/tmp/decodesubject" returns (0,"Subject:.*RequestID:[ \t]*([0-9]*)")
action tag "ticketno" value "%[command1]" continue

请注意，要获取命令的正则表达式中的捕获组，pipe您似乎不能使用%1但必须使用"%[command1]"。
