[Bldg-sim] ADMIN - Bounces from yahoo and others causing unsubscribes

[Jason Glazer]

Yesterday I received notice that over 100 people 
unsubscribed from BLDG-SIM all at the same time. This was 
very suspicious and so today I manually resubscribed those 
people to the mailing list. Most of the messages were for 
subscribers with Yahoo or Hotmail addresses although there 
were some others as well. Upon investigation I believe it 
was the automatic "bounce" processing of the mailing list 
software that got tripped up from a change by Yahoo back in 
April. Essentially, the mailing list keeps track of messages 
that get bounced back from certain addresses and if it 
happens too often it assumes that the person has abandoned 
that email account and unsubscribes them from the mailing 
list. Unfortunately, because of a way Yahoo has marked some 
of its messages, this is happening erroneously. I am not 
sure what I can do about it at this point but will continue 
to investigate.  Here is an article about the whole topic:

If you have a Yahoo or Hotmail address (or any other 
address, I suppose) and at some point in the future notice 
that you are not receiving email from the BLDG-SIM mailing 
list, please check the archives and see if you really have 
missed any email:

http://lists.onebuilding.org/pipermail/bldg-sim-onebuilding.org/

If you have, please try to resubscribe by sending a blank 
email to:

bldg-sim-subscribe at onebuilding.org

If this happens more than once, please let me know.

Sorry for the inconvenience.
