I have a strange problem on a customer's XG210 (SFOS 18.0.5 MR-5-Build586). We have been granulating the Filetype-Filter in the E-Mail Protections Mailpolicy. We recently added the MIME-Types for Macro-Enabled officefiles to the Filter
application/vnd.ms-word.document.macroEnabled.12, application/vnd.ms-word.template.macroEnabled.12, application/vnd.ms-excel.sheet.macroEnabled.12, application/vnd.ms-excel.template.macroEnabled.12, application/vnd.ms-excel.addin.macroEnabled.12, application/vnd.ms-excel.sheet.binary.macroEnabled.12, application/vnd.ms-powerpoint.addin.macroEnabled.12, application/vnd.ms-powerpoint.presentation.macroEnabled.12, application/vnd.ms-powerpoint.template.macroEnabled.12, application/vnd.ms-powerpoint.slideshow.macroEnabled.12, application/vnd.ms-powerpoint.slide.macroEnabled.12
This list here is regarding the MIME-Types for Post Office 2007 Macro-Enabled Filetypes which works accordingly. Now I wanted to Add the Pre-2007 filetypes, which didn't differentiate between Macro-Enabled File and Non-Macro-Enabled filetypes. Since this is an old standard I added the MIME-Types as well to be filtered:
But when I do this post Office 2007 Filetypes, that are not macroenabled are beeing filtered too. These Filetypes are pptx, docx and xslx. I tested thoroughly by creating new Testfiles and als checking the MIME-Type manually with Tools.
They were recognized as the following, which are obviously different.
Is this a known bug? I couldn't find anything regarding this Problem. I already contacted Sophos Support, but it's rather exhausting, since they still don't understand my issue and I don't want to waste anymore time.
Thanks in advance for your help!
my ticket got escalated to a Global Escalation Specialist. After I told him I would try to update the appliance, he said that an update would probably not help. This problem was already…
