This isn't a good way to run things. For example, unless the SMTP From:
line is reset, any errors in delivery will go to the message sender who
can't do a thing about them. Far better to reset the SMTP From: line
to be that of the list owner. Here's an example group of aliases that
will eliminate the timeout problem and send errors to someone in a position
to fix them without any changes to sendmail:
owner-kerberos: jik
kerberos: "|/usr/lib/sendmail -om -oi -fowner-kerberos kerberos-ml"
owner-kerberos-ml: jik
kerberos-ml: p-pomes@uiuc.edu,
jik@cam.ov.com,
etc@etc,
...
For really active&large lists, add -odq to the sendmail flags to delay
delivery until the next queue run. Obviously replace jik with the real
list owner.
