OTRS PostmasterMailbox.pl 解析/MIME 类型

Question

从 Ubuntu Server 12.04 升级到 Ubuntu 14.04 LTS 后，我开始遇到解析问题 与我的 otrs 安装。 我使用 mysql 5.5 和 perl 5.18 运行 OTRS 3.1.1。 我认为这可能是因为我有一个旧的 OTRS 版本，所以请按照以下步骤操作 OTRS 手册决定升级到 OTRS 3.2.1、mysql 5.6 并将几乎所有 perl 模块 + apache 升级到 2.4.7

我这样做了，一切正常，但解析问题仍然存在。 OTRS 通过 cronjob 使用脚本从邮箱中获取电子邮件并创建票证。 在许多票证上，它无法解析它们导致系统挂在特定邮件上 并连续打开同一张票，然后死掉（不解析队列中的其他邮件）。

有什么想法吗？

Answer 1

您发布了很长的错误消息，主要是 perl 5.18 中正则表达式功能的折旧警告。

实际问题是这样的：

open body: Invalid argument at /opt/otrs/Kernel/cpan-lib/MIME/Entity.pm line 1872.

该问题也是由 Perl 5.18 中的更改引起的，并已在 OTRS 3.2.12 中修复。您应该将您的 3.2.1 升级到 3.2.x 的最新补丁版本。 http://bugs.otrs.org/show_bug.cgi?id=9832

编辑：它也已在 3.3.1 中修复，因此如果您升级到最新的 3.3.x 补丁级别版本（即此时的 3.3.8），您也可以！

顺便说一句，在后来的 3.2.x 版本中，正则表达式折旧警告也消失了！
