Emails with wmz files being sent to system quarantine
We've had Fortimail for a few months, and have only recently discovered that emails with wmz attachments are being moved to system quarantine. Probably about 20, from perhaps 4 different senders, over 3 months. Important emails that need to get through.
It appears that these attachments are small images used in some senders' signatures.
Fortinet tech support has advised deleting the executable_windows file filter from the CF_Inbound content profile. That seems a bit extreme - I think it would also allow through exe files and many others. They say there's no way to strip them from the emails instead.
Can anyone please advise:
- are you also seeing these attachments resulting in quarantined emails?
- is allowing them through the appropriate course of action? Should I instead be advising the senders not to include them? (I assume they have no idea they're doing this, and won't know how to fix it.)
- is there a safer way to let them through?
