Okay, so basically Exim's quota support is complete garbage because it's
just not practical.
Instead, I should better do it all myself. By an external service that
determines the mailbox size and stores the result in the database along
with the other per-account data. This can then easily be checked at SMTP
time. The external service updates that database flag regularly (to
unlock soon after the user has deleted messages), and also after a new
message was written to the mailbox (to lock it quickly and not go too
far over quota).

Betreff: [exim] Verify recipient with mailbox quota at ACL time

Either that or do a manual job in ACL coding that evaluates a
maildirsize file. It's pretty unpleasant, but can be done.
There's a long-standing enhancement request for this -

Obviously nobody has ever had the energy,
I just need that calculation to run in a way that it's available at RCPT
ACL time. I was hoping that the verify=recipient directive had some
option for that, or so.
Nope. Recipient verify only goes as far as the routing, for local
deliveries, and the quota-calc knowlege is in the transport.
The other thing I do is set a DB flag for over-quota. Checking that
(along with everything else that is per-account) is simple in ACL.
