Response (I'm very sorry that I lost the address of who sent it):

We have the maximum message size set to 3 megs. What I would really like
is for sendmail to check for that error (user expired due to being over
quota), and bounce the e-mail back to the sender (with some error
message) instead of queueing it. Thank you.
