Just for the record (if anyone's interested), the offending account turned out to be: John Doe <[log in to unmask]> Thanks for everyone who offered helpful suggestions. Do you think it's worth pursuing with INAME.COM's admin to let them know someone was using their service for a less than honorable purpose?

Meeting" <[log in to unmask]> >Gregg Johnson <[log in to unmask]> >John Doe <[log in to unmask]> >Mark Nottingham <[log in to unmask]> >Zed Hyckx <[log in to unmask]> There are 2 ways to deal with this. One is simply delete all the iname.com subscribers. This of course cuts off the good as well as the bad, but if it's an average list, only 2 of the 5 will likely complain, which means you had 2 other dead weights. If you are a nice guy however and willing to do a little detective work, try this command: QUIET SET listname FULL822 FOR *@INAME.COM This changes how messages are sent for these users, putting the subscribed address in the To: field. Then ask the user to forward the next list mail, so you can see the address as subscribed that he/she receives. Then it's easy to remove the proper one. Don't forget to reverse the above with the command: QUIET SET listname FULLHDR FOR *@INAME.COM Do not leave people set to FULL822 for very long and do this only for a few subscribers at a time, otherwise it will have a noticeable and severely negative impact on the server performance. Since the server is question for this list is one of ours, we like to keep it running smoothly as possible.
