It looks like listserver.digitalriver.com is actually a CNAME for
ntls.digitalriver.com.

Many (but not all) mailers rewrite CNAMES, so my guess is that some
of your users' mailers are rewriting their mail from being to
listserv@listserver... to being to listserv@ntls... and others are
leaving it as to listserv@listserver...

With your old settings LISTSERV would only accept mail that was rewritten.

Would this explain it?
