I'm curious why you're classing meta-list with remarq. Meta-list
looks like an innocuous competitor to liszt.com to me. Yes, it has
s*bscribe/uns*bscribe links on each page but those are simple mailto
convenience links for your personal mail software. There's no
archiving or mail redirection.
Remarq required accounts set up so you would read the mail in their
webmail browser. I don't see any signs that meta-list is doing
anything like this.
Is there something you saw that I missed?
