thanks, dkblinux.
As you see in the snipit I posted in post # 17, another listserv that I participate on has had similar issues. Apparently, if I understand correctly, the providers see this email as spam until it is correctly identified as email. Also, if someone decided they no longer want to get, for example, auto-notification and they label it as spam (in order to stop gettign the emails) instead of changing their settings, this has caused a big mess becuase again the provider then thinks the emails to everyone are spam. You might want to be sure to let all posters know that if they no longer want to get autonotification or notice of PMs they should NOT mark it as spam, but instead change their settings. In my other forums it was such a problem that posters were warned of possible loss of posting priviledges if they did that.
