In early 2005 I changed all my mailing list subscriptions from an
address of lists04@ to lists05 @
(This is a process I'll repeat next
month. I do this to reduce receiving spam sent from trojan/virus
infected computers of my fellow list subscribers, and due to when a list
subscription address is leaked out onto the web and scarfed by a spammer
bot, both unfortunately common occurrences these days.)
Yesterday a list hosted on LISTSERV @
started sending me duplicate posts. The headers revealed that I was
getting one message sent to the old lists04 address and one sent to the
new lists05 address.
By itself this just looks like a problem on one server. But then a
different list hosted on LISTSERV.DARTMOUTH.EDU started doing it, and
another list on MAJORDOMO @
EDU started doing it today. Three
different institutions (INDIANA.EDU, DARTMOUTH.EDU, and MERIT.EDU)
running two different MLMs (LISTSERV and MAJORDOMO) created this problem
on 3 different lists.
This is not a case of the lists04 address suddenly resurfacing as one of
the list managers suggested was the cause. That address has been
getting email (100% spam) all along, 73 spams in the trash box over the
past 5 days (since I last scanned and emptied it). The only reason I
saw the duplicate list email is that I have whitelist filters for my
mailing lists before my spam filters and lists04 is used as a spam filter.
These lists are managed by people who typically just remove the problem
address rather than look deeper at the cause of why this happened.
So... I was wondering if any other list managers have seen this happen
with their lists in the past or in recent days? Or if anyone has any
suggestions where to look for the source of this problem?
