Acutually if the "list" is managed via a ":include:<file>" syntax in an
aliases file (the way majordomo does it)

XXX:                    "|/usr/lib/majordomo/wrapper resend -l XXX XXX-list"
XXX-list:               :include:/var/lib/majordomo/lists/XXX

Sendmail sends the message to one reciepient at a time ... waits for each
message to be accepted for delivery (or return an error) and then moves onto
the next reciepient.

As you can see the last person on the list was mailed 3 mins after the message
was recieved by the mailserver.

I can't show you the addresses, BUT you can take my word that serveral of the 
list members are on the same host (infact 2 list members are on the same
machine as the mailserver itself)

Anyway .... I don't want to get caught in the middle of a religeous war, One
you and Christian have ahd before)  I just wanted to show that Matt's view on
sendmail and lists was, seemingly correct.

Yours Tony.
