Michael,
LISTSERV does use the mailer from DOMAIN NAMES. LISTSERV applies a
strict interpretation of the file, in that it expects the :nick to be
a complete domain string. Your entry says:
------------------ Start of included file DOMAIN NAMES -----------------
:nick.BU.EDU :mailer.MAILER@BOSTONU BSMTP 3
:site.Boston University Local Area Network
:gatemast.Gatemast@Bostonu
------------------ End of included file DOMAIN NAMES -----------------
LISTSERV interprets this as only applying to node BU.EDU, not to xx.BU.EDU.
This is also the case with MAILER, I believe. You shoould correct the entry
to start ":nick..BU.EDU", as do most others in DOMAIN NAMES.
