    Hey all,
    My colleague was unexpectedly booted from the Code4Lib list and received
    the message below. She uses a work Gmail account so it doesn't seem
    especially likely to be misconfigured. I didn't realize there were any
    additional requirements for the new listserv, I wonder if this is affecting
    others.
    
    Any thoughts on how to fix this?

    You  have been  automatically removed  from the  CODE4LIB list  (Code for
    Libraries) as a result of repeated  delivery error reports from your mail
    system. This decision was based  on the list's automatic error monitoring
    policy and has  not been reviewed or otherwise confirmed  by a person. If
    you receive  this message, then it  means that something is  wrong. While
    you  are obviously  able  to  receive mail,  your  mail  system has  been
    regularly reporting  that your account  did not  exist, or that  you were
    otherwise permanently  unable to receive  mail. Here is  some information
    that may assist you  or your local help desk in  determining the cause of
    the problem:
    
    - The failing address is [redacted]
    
    - The first error was reported on 2016-09-08.
    
    - Since then, a total of 3 delivery errors have been received.
    
    - The last reported error was: 5.7.1 550-5.7.1
    [2600:3c03::f03c:91ff:fe55:a961]  Our  system   has  detected  that  this
    550-5.7.1 message  does not  meet IPv6  sending guidelines  regarding PTR
    records   550-5.7.1   and   authentication.   Please   review   550-5.7.1

    Please do  not ignore  this message.  While you  can re-subscribe  to the
    list,  it is  important  for you  to  report this  problem  to your  mail
    administrator so that  it can be solved. This problem  is not specific to
    the CODE4LIB list and may also  affect your private mail. This means that
    you may have  lost some private mail  as well. Anyone trying  to write to
    you during  the same time frame  might have received the  same errors for
    the same reason.
