On the mailing lists I run, closing the list to non-members has stopped what little spam we get -- it bounces to the list owner. I guess we haven't attracted any crafty spammers yet.

I just moved all my majordomo lists to onelist, since I'm getting off the ISP that was hosting them. You avoid spam at the cost of seeing an ad with each message, choose your poison. Onelist has a lot of nice features, though ...

That's the problem with majordomo, but with some of the other list servers, including onelist, you can set "nomail" mode on all but the primary. So when I'm using a webmail thingie to read email, I can also reply.

I use this address only when I am away from home. I have
reply-to set to dhr@iname.com and I read email sent to that
address from here, so please don't use the yahoo address.
