Microsoft Defender "Dynamic Delivery" is chopping off attachments

Our IMAP server is set up with something called "Dynamic Delivery", which replaces each attachment with a link to the file stored on a server. It then scans the file and replaces the link with the original attachment.

The problem is that I'm using a filter to remove the message from the server immediately, so I get the "stripped' copy of the file with just the link, and evidently the link is invalidated once the message has been scanned.

Is there a way to get Thunderbird to delay before downloading messages? I think that would solve the problem almost always. I don't want to have to leave the messages on the IMAP server, there's a retention cutoff and I want my messages to persist.

I should have phrased it:
