Last November I was "automatically removed from the SCIENTIFIC-LINUX-USERS list (Mailing list for Scientific Linux users worldwide) as a result of repeated delivery error reports from your mail system." So one possibility is that your mail system is occasionally failing to deliver mail to you from this list, but you haven't yet been removed. In my case, the reason was that the listserver sometimes sends email with a header longer than 32768 bytes, which the SLAC mail system couldn't handle. FermiLab said such long headers are becoming necessary because "cloud systems that everyone has and will be moving to, add additional diagnostic info in the headers so if people report any errors, they can more easily be diagnosed." The solution was to convince the managers of SLAC's mail system to increase their incoming header size parameter. Steven Yellin On Wed, 21 Jun 2017, Bill Maidment wrote: > Hi.
