The NANOG list has been running with sendmail, majordomo and bulk_mailer
on a long-suffering SPARC 5. This is the reason for both the lag time
and the lack of Precedence: header (bulk_mailer strips it out by
default; I don't know if running it thus was a policy decision or simply
an oversight). On and off for the last few days I've been using you all
as guinea pigs in my evaluation of Postfix on an Ultra 5, and so far it
looks promising. Delivery times are down quite a bit. To use you as an
example, Mikael, the current setup took between 9 and 14 minutes to make
deliveries to you yesterday. Routing the list traffic through Postfix on
the faster machine dropped that to 60-100 seconds. And as several people
have noted, the Precedence: header is preserved.

It's a little early yet to make a wholesale switch to the new system,
but I'm hoping to do so in January. If nothing else we'll be on the
better hardware. Bear with us a little longer.
