Hello David,

NO! My mail storage is mdbox. And at the moment I have no intention to convert it to Maildir! Could I ask why? maildir is a better storage format is almost every respect.
well, I have a mailbox with about 50k emails ..., so one reason seems
to me better backup performance with mdbox, since there are much less
files to save.
Another reason - you can beat me for this - it's more freaky ;-) - no,
just kidding ...
There was some years ago an interesting lecture from Peer Heinlein
about the mdbox mail storage, I afterwards bought his "Dovecot Buch"
of OpenSource Press and sticked to mdbox.
But I'll test backup of my mail storage converted to Maildir (which
can easily be done thanks dsync)
- If there are no significant time difference, I might then change to Maildir.

The thing is that users will usually open emails shortly after they
arrive. Most emails are not opened again later, especially the
attachments.
you're right about this. And if a user has suspicions abaout a
possibly infected attachment, one can delete the whole email without
hassle.

For my day job I work for Sophos (A cyber security vendor), so all
this is familiar to me. If you have the budget for a commercial
product, then Sophos PureMessage does have postfix support.
Technical details here:https://docs.sophos.com/msg/pmx/help/en-us/msg/pmx/tasks/GSGConfigExtPostfix...
Other AV vendors probably have similar support, but I don't know any details.

I know about Sophos. Since my infrastructure is only for me and my
family, I'll use the SAV9-free package ... and will try to integrate
this with Postfix or AmaVisd.
