ListOwners, I own a small list ([log in to unmask]) in which I limit subscription by having * Subscription= By Owner. Unfortunately a prospective subscriber sometimes sends me his/her e-mail address (on paper) and it is wrong! Usually when I subscribe such a user Listserv quickly lets me know that the address is incorrect and I can contact the user and get the correct address. However, recently I had a couple of addresses which were wrong (I know this because when I e-mailed them directly I did get an error message returned) but Listserv flagged up no fault when they were subscribed. I have not set any "Errors-to" path so I presume that all errors should come back to myself. Any ideas ?
