Sure there is...  Just subscribe then sent a message to
LISTSERV@gerry.vanagon.com with the content SET VANAGON NOMAIL. To quote
the lsoft manual for listserv:

Options that may be set

Mail/NOMail

Setting this option to Mail indicates that you will receive mail from
the list. NOMail is the complementary command that stops mail but leaves
you subscribed to
the list. (NOMail is often a good compromise for users who are leaving
the office for vacation or on extended business trips, and who don't
want a full mailbox
on their return.) The format of the messages received is controlled by
the DIGEST/INDEX/NODIGEST/NOINDEX options (see below).

Please note, if you use an auto-responder while on vacation without
setting your subscription options to NOMail, your "vacation" messages
may bounce back to
LISTSERV and you may be "served off" from LISTSERV when you return. This
is because LISTSERV will be unable to process the message from your
auto-responder and will consider it an error. Being "served off" simply
means that any commands you send to LISTSERV will be ignored until
someone else
sends a SERVE command on your behalf. See Appendix E for more
information about the SERVE command.

note:  SEND THE NOMAIL COMMAND TO <mailto:listserv@gerry.vanagon.com>
NOT THE LIST!!!
