message dupes anyone ?

Hi folks, 

is it just me or are there a lot of dupes of mails coming from this list?
Obviously noone else is complaining so it might be on my side though I 
can't think of a source.
I've got simply Mozilla-Mail 1.7.11 colecting the stuff off  my 
provider's pop server along with some other lists. Mozilla sorts them 
into message-folders and thats it.
I took a little survey and found pg-general and pg-sql not affected but 
pg-novice has the dupes, too.
The funny thing is that not every single mail gets cloned but quite a lot.


Any hint ?

Andreas
