I cannot work out when postfix 2.3.3 was released...there was a bugfix 
related to anvil in Dec 2005 and I am using 2.3.5 without this 
particular problem. Speaking of which, it is time for me to upgrade to 
2.3.13 or the latest 2.4.x . You might want to turn on debugging to find 
out what is going on with anvil.
