Hal, The problem with this approach is that many companies use an outgoing email address that is different/modified from the users incoming address, so users would have to register both addresses (once they figure out that they have 2 addresses). I had this problem with a list that I maintained, so I found it easier to open it up to allow anyone to post to it. Les Brown At 08:46 AM 9/26/2001 -0400, you wrote:

Greetings,

There is also another way to limit posting to the list that does not involve the two-step process. The list can be limited so that only those registered for the list can post to it. I know that is a feature of majordomo that I use for some of my lists.

Dear ITU-SG16 Experts:

I have noticed a dramatic increase in SPAM on the ITU-SG16 mail list. As administrator of the list, I would like to hear about a proposed change that will decrease the amount of SPAM and other mail messages including potentially harmful email (viruses, etc.).

I can set LISTSERV to require the sender of a message to acknowledge the message before LISTSERV will send it. So to send a message, you would send it in the usual way but before it gets sent to the mail list, LISTSERV will send you a message. If you respond to the message, you authorize LISTSERV to send the message. Since most SPAM is spoofed, the "sender" will not acknowledge LISTSERV and the message will not get sent.

I would appreciate hearing if there are any concerns with this method before I implement it. I will follow-up this email later to announce what action I have taken to this ITU-SG16 list.

Thank you,
