A user on daily-article-l has been reporting that they have been receiving multiple (between 4-10) copies of emails sent to the list. They've reported it via OTRS (see Ticket # 2009030410049508 or above URL). Can contact them if further information is needed to figure out the problem.
Similar issues were reported in #wikimedia-tech for another mailing list (I'm trying to figure out which other list that was).
