Brian Kantor (brian@ucsd.edu) offered the following well-thought-out
series of /usr/lib/aliases entries for mailing-list redistribution with
errors, including downstream errors, sent to a specified address
("brian@ucsd" here).  I don't think "-odq" is necessary, it just trades
distribution latency for possibly reduced peak load.  Downstream messages
have a 'From ' and SMTP 'MAIL FROM:' address of 'tcp-group-request',
so errors are sent there, but the 'From:' line remains the original sender.

   tcp-group-request:brian@ucsd
   tcp-group: "|/usr/lib/sendmail -odq -oi -ftcp-group-request tcp-group-list"
   tcp-group-list: :include: /usr/net/mail/maillists/tcp-group
   owner-tcp-group:postmaster@ucsd
   
   That way the mail appears to come from the -request address, so all the
   errors go there instead of to the message originator.
