Even when running with Netdata support, LISTSERV tries to fold long lines
both so that they look better in the archives and to avoid ending up with
outrageously long lines  that SMTP will not be able  to process, if there
were many  "To:" recipients  for instance  (the only  thing worse  than a
massive spam is  a massive spam that brings some  mail systems down). But
in this case LISTSERV incorrectly  used the folding algorithm for address
lines, where it is indeed ok to split around a period. A fix is available
from [log in to unmask] for customers with a service contract.
