Yes, I'd love it. It would be great to have several steps:
1) warning if quota reaches 85% or so (definable)
2) error if quota reaches 100%
in both 1) + 2) the user should receive an e-mail, which can add to 
quota, no problem, but it should be sure it can be delivered (not 
rejected because of full quota).
Also, this message should be sent immediately when reaching the quota, 
and in addition with dbmail-util. The message itself should be 
definable, and we should see which user/domain it's for, to send the 
message in the users language.

BTW, it would be nice to have quotas count in a way, that if a user has 
a mailbox of 5MB, with 1MB left, that if a message arrives that has 2MB 
or even 10MB gets delivered, and only the *next* messages are rejected. 
Something like "loose quotas", so you can give users only a small 
space, and still allow them to receive at least an e-mail of the 
max-mail-size the mailsystem allows (which is 100MB for us).

We extended dbmail to have domain and customer tables also, and have 
prepared per-domain and per-customer quotas. So you can have a domain 
with 50 users each having 500MB mailbox, but the domain itself is 
limited to 5GB, and if the customer has other domains you can define to 
have 10GB for all domains of this customer together.
There's another table defining who to contact when domain/customer quota 
is (almost) reached.
Currently, these are no hard limits, we just get a notice, and see which 
customers need more space, to adapt prices.
