After thinking a bit more, another possibility occurred to me. 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.
