With mlmmj there's a seperate 'version' of the list, just like the way digests are done in ezmlm. If you send a mail to listname+subscribe-nomail@domain.tld you subscribe to the list without getting any email from it ever. Handy if you read your lists via the web, or through a news gateway. So what could be done simply treat postings to a subscribers only list from emails not subscribed, as if they were trying to subscribe to the nomail version of it. This way they only need one reply, and they are allowed to post from this address. To do it right, the mail that was originally sent, will of course be posted to the list, if the person subscribes to the nomail version--a little bit like moderation. -- Mads Martin Joergensen, http://mmj.dk "Why make things difficult, when it is possible to make them cryptic and totally illogical, with just a little bit more effort?" -- A.
