嵌入式favicon为何会破坏电子邮件服务器?
我已经向一位同事发送了一封电子邮件,其中包含以下html代码(嵌入式图标)粘贴在Thunderbird中: <link rel="shortcut icon" href="data:image/vnd.microsoft.icon;base64,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"/> 然后他的Outlook停止接收错误0x800CCC0F(服务器连接问题)的电子邮件,它没有收到“毒药”电子邮件。所以我虽然是邮件服务器的问题。 但我的问题是,为什么“简单”的文本会破坏电子邮件服务器? 这是发送消息的主要部分: Content-Type: multipart/alternative; boundary="------------040701090409010309050003" This is a multi-part message in MIME format. --------------040701090409010309050003 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: quoted-printable <link rel=3D"shortcut icon"=20 href=3D"data:image/vnd.microsoft.icon;base64,AAABAAEAEBAAAAEAIABoBAAAFgAA= ACgAAAAQAAAAIAAAAAEAIAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= AAAAAAAAAAAAAAAAAAAAAAB+s8sQfrPL/H6zyxAAAAAAfrPL/H6zy/wAAAAAfrPL/H6zyKh+s= 8v8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH6zy/wAAAAAAAAAAH6zy/x+s8k8AAAAAA= AAAAB+s8v8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH6zyxB+s8v8frPLEAAAAAB+s8v= 8frPL/AAAAAB+s8v8frPIqH6zy/wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= B+s8v8frPL/H6zy/x+s8v8AAAAAH6zy/wAAAAAAAAAAH6zy/wAAAAAfrPL/H6zy/x+s8v8frP= L/AAAAAAAAAAAfrPL/AAAAAAAAAAAfrPL/AAAAAB+s8v8AAAAAAAAAAB+s8v8AAAAAH6zy/wA= AAAAAAAAAAAAAAAAAAAAAAAAAH6zy/wAAAAAfrPL/H6zy/wAAAAAfrPL/AAAAAAAAAAAfrPL/= AAAAAB+s8v8AAAAAAAAAAAAAAAAAAAAAAAAAAB+s8v8AAAAAAAAAAAAAAAAAAAAAH6zy/x+s8= v8frPL/H6zy/wAAAAAfrPL/AAAAAAAAAAAAAAAAAAAAAAAAAAAfrPL/AAAAAAAAAAAAAAAAAA= AAAB+s8v8AAAAAAAAAAB+s8v8AAAAAH6zy/wAAAAAAAAAAAAAAAAAAAAAAAAAAH6zy/x+s8v8= frPL/H6zy/wAAAAAfrPL/AAAAAAAAAAAfrPL/AAAAAB+s8v8frPL/H6zy/x+s8v8AAAAAAAAA= AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA//8AAP//AADiVwAA9u8AAOJXAAD//wAA//8AAIWh= …
