I don't want to enter this debate, but I have to say just one thing: the
EB0UB011 server has been chronically screwed up since about the time
Jose-Maria left the place. The degree of screwup has indeed increased at
about the same time LISTEARN was installed, but it may or may not have
been a direct consequence. The one thing that is clear in this mess is
that the people who were in charge of the server at that time were pretty
unresponsive, to use gentle words, and mail to Postmaster returns "no
such local user" while the registered technical contact had moved to
greener pastures and nobody bothered to read his mail regularly.
