I'm not a mail expert, but I think I understand what is going on here due to
changes made recently by my ISP.
As far as I can tell, relaying is when you ask a smart mailhost (aka SMTP
server) to send mail to a user who is not on their network. Virtually all
ISPs will prohibit this because it allows *anyone* to send mail via their
system without having to be a member.
My ISP will only allow mail through their smart mailhost (post.demon.co.uk)
if it is from a demon subscriber (trapped by IP address, I guess).
I cannot explain why LISTSERV should be doing this, unless something is
misconfigured.

I don't think it is LISTSERV that is relaying. Say you send a message to
[log in to unmask] and you connect to fred.siteB.com and ask it to send your mail
to [log in to unmask] . If you are not a customer of siteB.com then you would be
"relaying" your message to site A.

I've never seen this on my list, but its one that should be discussed with
your listserv postmaster, and/or LSOFT themselves.
