MIME issues

Question

Hello 
 
 I had a virus attachment in this file below however savscan was simply returning a (corrupt) error 
 Could not check /spam/11857--99734.eml/AW'20 NEW ORDER.doc (corrupt) The doc was not corrupted and luckly my desktop computer (Kaspersky) blocked it . After investigation savscan failed due to MIME attachment extraction error 
 in the email body I found this 
 Content-Disposition: attachment; filename="AW'20 NEW ORDER.doc" 
 as it seems savscan was not able to extract the attachment because there were a single quote ' , in the filename 
 I have seen this problem often in other similar situations, if the filename is not well formatted or if there are special chars inside. 
 
 Do you have in plan to fix this or is it better I use an external MIME attachment extractor to scan attachment in email received ? Thank you

Hi Kaneki 
 To scan the email attachment before receiving the emails to your exchange server there is Sophos Email Appliance and Sophos central Email gateway available who does email scanning and also provide spam protection and much more protections. 
 If we talk about the above point, If there is an error while extracting the attachment from the email, it may fail to scan the attachment. I'd suggest you use Email gateway or a similar product to do the email scanning before it reaches your mailbox.
