On my servers this usually means mailbox is out of quota. If that is not the case, you should look in your maillog and search for delivery immediately preceding first 456 message for given address. Maybe the message is still in the queue, in which case mailq could give useful info as well. Basically, everything should be in maillog. I have no experience with spamassasin, with regard to clamav there is question how are you using it. If there is scanning running too long, you should see in maillog - there are timestamps for message reception, delivery begin etc. Just examine everything relevant into detail.
