I'm sorry if I didn't make myself clear before, but this is my problem: I created an "Announce-Only" list from the web interface for Site Maintainers. The resultant header for the list works fine. The Owner/Editor was able to post messages (with confirmation) to the list and the messages were being disseminated correctly. I then added the FILTER_ALSO control variable in the "go.user" file and the Filter= keyword in the header file as shown below. (These were added because I didn't want people with addresses that end in "@hud.gov" to be able to subscribe themselves. I still want all others, though, to be able to subscribe themselves as before.) When I added the filters, the owner was not able to post any messages. Specifically, when he posted the message he would get a confirmation message as expected. But then, when he replied to the confirmation message, LISTSERV would kick the "ok" message out as an error and send it to the Site Maintainer, which is me. The error message that I received is "mail origin seems to be a mailer". This is the part that I don't understand. Why does LISTSERV kick this out as an error when I add the filter, but it works fine when the filter is not there? By the way, "owner1" is a made-up name that I used to protect the name of the real list owner. "owner1" is not actually in the header. But thanks for the info, it will help in the future.

This is in LISTSERV's built-in filters and will only cause problems. Postmaster@..., Adminstrator@... are alos not usable. I suggest something like listmgr@... which is not in the built-in filters. > * Editor= [log in to unmask] > * Filter= Also,Allow,[log in to unmask] Remove these 2 lines. >I've set up the go.user file (Unix-based system) to include the FILTER_ALSO >control variable as follows: > > FILTER_ALSO="*@HUD.GOV" > >so that I can prevent HUD employees from posting and subscribing to all >lists. You don't need this. See above for better subscription control method.
