C# 如何防止Sitecore EXM新闻稿将链接转换为RedirectUrlPage.aspx

我想阻止Sitecore EXM发送的电子邮件中的某些链接转换为“../Sitecore/RedirectUrlPage.aspx…”。具体来说，我不希望我们的图像src URL（如“”）转换为任何其他URL，从而阻止图像显示在电子邮件中

查看后，我基本上意识到我的Sitecore.EmailExperience.Core.config中的以下设置是控制EXM电子邮件中的URL转换为“../Sitecore/RedirectUrlPage.aspx…”的功能：

<processor type="Sitecore.Modules.EmailCampaign.Core.Pipelines.GenerateLink.Hyperlink.GenerateHyperlink, Sitecore.EmailCampaign" >
    <RedirectPagePath>/sitecore/RedirectUrlPage.aspx</RedirectPagePath>
    <UrlQueryKey ref="settings/setting[@name='QueryStringKey.RedirectUrl']/@value" />
</processor>

你知道我应该如何修改上面的代码以防止它操纵任何图像src URL吗？我猜有一个特定的情况（if条件）会阻止某些行执行，或者阻止某些逻辑执行。我尝试了30种方法，但都没有效果。谢谢

        stringBuilder.Append(args.MailMessage.ManagerRoot.Settings.BaseURL);
        stringBuilder.Append(this.RedirectPagePath);

        if (args.QueryString.Count > 0)
        {
            string str = NameValueCollectionExtensions.ToQueryString(args.QueryString, true);
            stringBuilder.Append(str);
        }

        args.GeneratedUrl = stringBuilder.ToString();
    }
