Priv. Message box full how to disable emailsent?

[newvbuser]

Hi if a user's PM box is full (reached the set limit I have for every user), then if another user send another PM to him, the program says "user's box is full, and we have sent an email to him about it"

Can I stop this ? I say this because there are tons users whose EMAIL boxes too are full (I bet they are full of spam emails), and it's kind of getting ridiculous because all these emails vb is sending out to such users is bouncing back to our accounts. We don't have time to sort out whose emails are bouncing back coz they number about 50-100 with error messages.

I just don't want any email to go out at all if a user's PM box is full and another PM is sent, just that the program should say "Cannot send PM to username, we recommend posting a message for the user to empty his/her PM box."

That's it.

If there is no solution to the above, is there a SQL query that'll list out users whose PM boxes have reached the limit?

Thanks in advance!!!
