[Mailman-Users] Mail going to list archives but not to list!

[Elizabeth Schwartz]

I'm running mailman 2.1.8  on Solaris 10 (06/06)

After working fine for a month, my mailman install broke this morning  (I
know something must have changed but I can't see what!) Mail sent to lists
ends up in /usr/local/mailman/qfiles/out . If I run unshunt, nothing
changes. If I run unshunt /usr/local/mailman/qfiles/out, the files go away
from the qfiles directory but no mail is received by the users.

I am not getting any error messages relating to this in any file that I can
see. Nothing in any file in /usr/local/mailman/logs, nothing in any system
or mail error files.

Tearing my hair out here. Thanks for any clues as to what might be causing
this or where to LOOK.
