请求跟踪器 4 html 邮件内联图像不可见

我正在使用 Request Tracker 4.0.15。

我的安装使用 getmail 将 html 电子邮件附加（或创建）到工单，但是，内联图像不可见：

<div dir="ltr">

<div>text text text text text

    <br><br><img><br><br>

</div>text text text text text text<br>

但是当我从 RT4 票务页面下载电子邮件并打开它时，图像是可见的：

<div dir="ltr">

<div>text text text text text

    <br><br><img alt="Inline images 1" src="<<removed>>"><br><br>

</div>text text text text text text<br>

我的配置：

Set($TrustHTMLAttachments, 1);
Set($AlwaysDownloadAttachments, 1);
Set($PreferRichText, 1);
Set($ShowTransactionImages, 1);

我还创建了一个包含以下内容的 Web_local.pm：

push @SCRUBBER_ALLOWED_TAGS, qw(A B U P BR I HR BR SMALL EM FONT SPAN STRONG SUB SUP STRIKE H1 H2 H3 H4 H5
H6 DIV UL OL LI DL DT DD PRE BLOCKQUOTE BDO IMG);

push %SCRUBBER_ALLOWED_ATTRIBUTES = (
