Although what you say may apply elsewhere, I too receive on occation a 
duplicate email...   and I don't believe it has anything to do with this list 
or others.

I have noticed that when a duplicate email comes through, the SIZE of the two 
emails are slightly different.  For example I have one here now that shows  
10.3KiB   and the dupe shows  10.4KiB.    This always appears to be the case 
(the fact they are different).    

I use fetchmail to fetch mail to my mail server and pass the emails to 
procmail to put them into mboxes.  Then various machines pick the mail up from 
the server using POP3.

One thought that has occurred to me is that somehow Kmail is picking up an 
email before it has finished processing...   and then picks it up again as a 
new email after it has finished.

It's a rare occurrence, as in maybe twice a day.   I receive less than 100 
emails total in a day....   But with the (ungodly) methods of Akonadi and all 
the other "resource" handling that goes on with Kmail these days, I haven't 
bother to look into it any further.
