2.99.27 on alphapc.dcs.ed.ac.uk, redhat-3.0.3 on an alpha pc64.
Again, no problems except very minor tinkerings.

BTW, we had a scheduled power maintenance one weekend, and the two
days' downtime caused quite a backlog of mail to pile up --- alphapc
does *.uk exploding of all vger's linux mailing lists.  Time to catch
up with the backup: approximately 2 to 2 1/2 hours.  Message delivery
for the first couple of hours was at the rate of over 10,000/hour
(equivalent to over a quarter of a million per day).  That was with
maxring=20 and nrouters=1.  Doubling the ring and adding 3 more
routers about doubled the throughput, but the backlog eased so soon
after that that I wasn't able to gather precise peak throughput
statistics.

Given that we are told that the router is probably the bottleneck in
zmailer if you've only got one running, I was pretty impressed at this
performance. :)  Thanks to the zmailer gods --- it's been nothing but
a rock-solid performer for the last month.

Cheers,
 Stephen.
