Fri, 10 Apr 2026 09:04:34 +0000 https://bugs.horde.org/ticket/7338 Bug in display of base64 encoded e-mails I receive sometimes some base64 encoded e-mails. Those are not correctly displayed by Horde. The specialty of those e-mails is that they consist of two base64 encoded parts. The message source looks like the following: MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="b1_c45b2h52c330849d3f58635b08353726" --b1_c45b2h52c330849d3f58635b08353726 Content-Type: text/plain; charset = "iso-8859-1" Content-Transfer-Encoding: base64 VGhpcyBpcyBzb21lIHJhbmRvbSBiYXNlNjQgZW5jb2RlZCB0ZXh 0LiBMb3JlbSBpcHN1bSBkb2xvciBzaXQgYW1ldCwgY29uc2VjdG V0dWVyIHNhZGlwc2NpbmcgZWxpdHIsIHNlZCBkaWFtIG5vbnV teSBlaXJtb2QgdGVtcG9yIGludmlkdW50IHV0IGxhYm9yZSBldCB kb2xvcmUgbWFnbmEgYWxpcXV5YW0gZXJhdCwgc2Vk --b1_c45b2h52c330849d3f58635b08353726 Content-Type: text/html; charset = "iso-8859-1" Content-Transfer-Encoding: base64 VGhpcyBpcyBhbHNvIHNvbWUgcmFuZG9tIGJhc2U2NCB lbmNvZGVkIHRleHQuIExvcmVtIGlwc3VtIGRvbG9yIHNpd CBhbWV0LCBjb25zZWN0ZXR1ZXIgc2FkaXBzY2luZyBlb Gl0ciwgc2VkIGRpYW0gbm9udW15IGVpcm1vZCB0ZW1 wb3IgaW52aWR1bnQgdXQgbGFib3JlIGV0IGRvbG9yZSB tYWduYSB --b1_c45b2h52c330849d3f58635b08353726-- IMP displays only the first part of the message (This is the footer, so it should be displayed at the end of the e-mail), while ignoring the 2nd base64 encoded part. Also note the content-type of the 2nd part (text/html). Mon, 15 Sep 2008 09:39:45 +0000 https://bugs.horde.org/ticket/7338#t48930 Please upload an example message. Though I bet it's broken c-client library on your server. Mon, 15 Sep 2008 10:39:40 +0000 https://bugs.horde.org/ticket/7338#t48934 How is this broken behavior? That is a multipart/alternative part - unless you have set the preference otherwise, you only show one part. Mon, 15 Sep 2008 16:22:24 +0000 https://bugs.horde.org/ticket/7338#t48946
