I have done the upgrade but still today I say atleast one mail
disappearing without trace 

Now I have 
MailScanner 4.63 ( latest-stable as of today) 
postfix-2.3.4
on Centos 4.4

That is it--
 the queueid doesnt figure  anywhere else in the entire maillog , nor is
it there in the mailq 

Is this mail lost then ? 

Thanks
