A few days ago I moved all our LISTSERV lists (over 500) from LISTSERV
1.8b on VM to LISTSERV 1.8c on AIX (lists.ufl.edu). All in all, it's gone
pretty well. (Mostly because I wrote a huge Rexx EXEC on VM to parse and
rewrite all the LIST config files.)
Since we expect to start hosting a very large number of lists (one for
every course section in the university!), we wanted to avoid the need to
login/rsh to the LISTSERV host when adding/deleting lists. That
specifically meant not updating /etc/aliases and running newaliases. I
was able to avoid /etc/aliases by configuring sendmail to use lsv_amin as
a local delivery agent! I am appending the sendmail.mc m4 file below for
your perusal; I'd also like to hear any suggestions you have for
improvements. (This sendmail config doesn't support file-delivery, so I
can't define ids in /etc/aliases that write into a local logfile, which is
something I'd like to be to do, e.g. as a place to direct list-errors to.)
I do have a couple of items on my gripe/wish list ...
The first (and most important) item is that we need an exit to be called
before logfile creation -- each of our lists has a primary owner on our
Unix system, and we store each list's logs in a subdirectory under their
owner's home directory. The purpose is for charging, but it doesn't work
under Unix because the logfiles are owned by the username 'listserv'.
We'd use the exit to create the empty logfile, change its owning-user to
the owner of the parent directory and its group to listserv's primary
group, and make it group-writable. This all worked automatically for us
in the CMS Shared File System.
The second item is that the SCAN command doesn't recurse down into
sub-lists. We make extensive use of sub-lists, and I had a
locally-written /WHOIS command for VM LISTSERV which would recurse down
thru sublists.

MAILER_DEFINITIONS
#-- OK, we've included the standard "local" delivery-agent rules,
#-- so now we need to replace the local delivery-agent definition with
#-- one that uses LISTSERV's lsv_amin program so we can avoid defining
#-- each LISTSERV list in /etc/aliases.
#-- Since we are defining our own local delivery agent which will delivery
#-- to listnames which are not enrolled as users, we must use /etc/aliases
#-- to auto-forward all special users, like root and postmaster and
#-- list-master, because sendmail won't be processing ~/.forward files.
#-- Purposely omit the following flags which are typical for "local" delivery:
#-- F=m - lsv_admin expects only one recipient list per instantiation
#-- F=r - ??? (I don't know why)
#-- F=S - lsv_amin is instead installed as setuid-listserv
#-- F=w - lists aren't enrolled usernames, so bypass /etc/passwd lookup
#-- U=u:g - lsv_amin is instead installed as setuid-listserv
#-- F=n - suppress prepending Bezerkley "From xxx" separator line
