I?m wondering if there?s a way to block someone from subscribing at all? Setting the errant person's address to NOPOST will prevent them from posting to the list, but if they unsubscribe, that setting gets lost. Putting them in the Filter= Also, baduser@address list is effective to prevent posting or subscribing. As Karen noted this List Header setting does support wildcards. Another thing only a LISTSERV POSTMASTER (i.e. Site Admin) can do is to command: Quiet serve baduser@address off drop This causes LISTSERV to forever ignore any/all emails from that address, regardless of whether an attempt to post a message, or any command such as subscribe, or even unsubscribe. Unfortunately the SERVE command does not support wildcards, so if the baduser keeps changing their address this can become a challenge to keep up. ############################ To unsubscribe from the LSTOWN-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTOWN-L&A=1
