Actually, I suspect it's name is listserv.edeliever.com, based on your
previous note where you failed to sanitize it.  Also, anonymizing it like
this is *not* helpful, because when we go to look in various config files
to see if your host is misregistered, we won't find Mylistserv.com.

Ahh... from the Site Manager's Guide:

10.3.10. Subscription summary updates (SUPD jobs)
X-SUPD jobs update the file used by "LIST SUMMARY". LISTSERV receives the file
from another LISTSERV host and distributes it down the line:

Did you perchance list this as a 'Backbone' server when registering it?

Did you specify some RUNMODE= *other than* STANDALONE?
