If you're talking about the MAIL FROM: line in the envelope being null (eg, <>), then you need to check your sendmail.cf file. The default sendmail.cf supplied with Solaris is *still* hopelessly broken and does not handle the valid RFC-specified case of a null MAIL FROM in the envelope (recommended for error daemons etc) correctly. The simple solution is to upgrade to a recent sendmail or fix the sendmail.cf ruleset 4 (I think -- it's been a long time) to handle canonicalization correctly for this case. In either case, it's not LISTSERV, but elements of your mail system that are having problems.
