OTRS PostmasterMailbox.pl解析/ MIME類型

Question

從Ubuntu Server 12.04升級到Ubuntu 14.04 LTS後，我開始用我的otrs安裝解析問題 。 我用mysql 5.5和perl 5.18運行OTRS 3.1.1。 我認爲這可能是事實，我有一箇舊的OTRS版本，所以遵循步驟 OTRS手冊決定升級到OTRS 3.2.1，MySQL 5.6和ugpraded幾乎所有perl模塊+ apache到2.4.7

我這樣做，一切正常，但解析問題依然存在。 OTRS通過cronjob使用腳本從郵箱獲取郵件並創建票據。 在許多故障單上，它無法解析它們，導致系統掛在特定郵件 上，並連續打開相同故障單然後死亡（不解析其他郵件隊列中的故障）。

什麼想法？

Answer 1

您發佈錯誤信息，Perl的5.18的正則表達式的功能主要是折舊警告的長期跟蹤。

實際的問題是這樣的：

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

這個問題也通過在Perl 5.18的變化引起的，而在OTRS 3.2.12固定。您應該將3.2.1升級到最新的3.2.x補丁版本。 http://bugs.otrs.org/show_bug.cgi?id=9832

編輯：它也已在3.3.1中修復，所以如果你升級到最新的3.3.x補丁版本發佈（即3.3.8在這個時候），你會沒事的！

在稍後的3.2.x版本中，正則表達式折舊警告也消失了！
