Deferred because of Outbreak protection or for Fortisandbox inspection.
Is there the possibility that I receive this email with some delay in opposite to a simple "accepted" email?
Regards,
Graziano.
Yes, definitively. Defered mails are delivered with some delay, like minutes, to be able to scan them. Mostly I see this with FortiSandbox which can take up to 30 minutes (the default hard limit). Depending on the number of URLs and the size and type of attachment a FSA scan takes 1-5 minutes.
FWIW: Greylist can also creat Deferred email delivery or path interruptions between the sender-receiver and so on
It's not a bad message btw.

For greylisting you should see delay rather than defer for the disposition
Will it needs to be taken in context of the sending MTA.
A greylisting ESA is going to delay the sender but at the same time the sender will have mail_queue as "message deferred". This is not a hard bounce or failure
Depending on the receiver and greylisting mechanism employeed ( ironport , postfixgrey , barracuda, etc..... ) you might get a nice 4XX messages or nothing at all.
Bottom line greylisting can cause a sender to have deferrals, same as any other AS mechanism like throttling.

You are right. I was only referring to what can be displayed in FortiMail logs as a disposition.
Cheers
I am still a bit confuse with Defer Disposition
not sure exactly how it works, any input will be greatly appreciated.
if you whitelist an email it would skip defer disposition?
Thanks
