Duplicated messages sent from the list

[Ralf Mardorf]

Hi,

sometimes I receive duplicated messages _from the list_ (no CC issue). It 
doesn't matter if I sent the mail or somebody else sent a mail to the list.
The mails I receive two times are just one time in the archive.

There seemingly is an issue with the list's mailman or with my Kubuntu Saucy's 
KMail.

rocketmouse at saucy:~$ kmail -v
Qt: 4.8.4
KDE Development Platform: 4.11.2
KMail: 4.11.2

Anybody experiencing the same? If so, what MUA do you use? I then would file a 
bug against Kmail to an Ubuntu bugtracker (not upstream) or write to one of 
the list masters.

Regards,
Ralf
