[contenttypefilter.pm, utils.pm, archivefilter.pm] Subject: [pmg-devel] [PATCH pmg-api v3 2/5] utils: content-type: don't fallback to header information for magic X-BeenThere: pmg-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox Mail Gateway development discussion <pmg-devel.lists.proxmox.com> List-Unsubscribe: <https://lists.proxmox.com/cgi-bin/mailman/options/pmg-devel>, <mailto:pmg-devel-request@lists.proxmox.com?subject=unsubscribe> List-Archive: <http://lists.proxmox.com/pipermail/pmg-devel/> List-Post: <mailto:pmg-devel@lists.proxmox.com> List-Help: <mailto:pmg-devel-request@lists.proxmox.com?subject=help> List-Subscribe: <https://lists.proxmox.com/cgi-bin/mailman/listinfo/pmg-devel>, <mailto:pmg-devel-request@lists.proxmox.com?subject=subscribe> Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: pmg-devel-bounces@lists.proxmox.com Sender: "pmg-devel" <pmg-devel-bounces@lists.proxmox.com> file-type detection based on content/magic is the single piece of information not determined by the headers of the e-mail, and thus not directly controlled by the sender. this patch removes the fallback to the content-type header mime-type in case magic_mime_type_for_file does not detect the type.
