 Since the update 9.410-6 yesterday, every email with a pdf file is unreadable and go in quarantine.

Hi Benoit, 
 Please show us associated smtp.log for the Email that is rejected and make sure the file type is not added in the block file extension in SMTP / malware section. 
 Note: Always upload the back-up from previous firmware after an upgrade. Any help with that? 
 Thanks

Hi Benoit, 
 Please change in Email Protection - SMTP - Malware - Malware scanning - from 'Dual scan' to 'Single scan' and change the AV engine from Sophos to Avira in Management - System settings - Scan settings - Single scan engine. 
 Any help?
