I had such a problem once, the /var filesystem was almost full (95%)
acutally, as qmail never runs as root, it considered it as totally full 
(the last 5% being usually reserved for root's only usage (depending on 
filesystem formating options choices)) and so, althought everything 
looked correct, qmail was very slow because it always had to wait until 
a few bytes were freed (by sending/routing a message out and deleting it 
from its queues) before receiving/accepting incoming messages
If this is the cas at your's, make sure to give more room to qmail by 
increasing /var size or deleting/moving other files
