Send a message addressed to firstname.lastname@example.org containing a single line in the following form:
with LISTNAME replaced by the name of the mailing list. Make sure that line is in the body of the message, not in the subject line. It should be the only line in the body of the message and start in the first column. The subject of the message is ignored by the listserv software and may be left blank.
Note that this method of removing oneself from a mailing list is universal for mailing lists using listserv and listproc software.
