Mail list delays

[Jeffrey A Law]

I haven't timed a message recently, but I suspect the multi-day
delay problem should be much better now.

Some recent changes we made to the mail configuration on Cygnus's
mailserver have reduced the size of the bulk queue to about 1/3
of its previous steady state size.  As a result I think messages
are getting to most recepients much quicker than before.

We've got more changes planned, but it will be a while before we
can implement them.  Hopefully the recent changes are enough to
keep things from getting too bad before we can put the long term
fixes in place.


I'm kinda hoping that the duplicate mail message problem was due to
a locking/race issue or some such that was exposed by the huge 
queues.  If not we'll have to do more digging.
