I used to have an external spam check so I disabled AS and AV in my 7.2.7 install. Now I enabled in order to block js attachments, but even if the blocked extension list doesn't contain PDF zimbra DOES block these files with BANNED CONTENTS ALERT. I also checked and the Block encrypted archives option is disabled. I restarted the whole Zimbra twice, but the block still persists.
What could it be?
Example of blocked notification:
No viruses were found.
Banned name: .pdf,Documento_giustificativo.pdf
