I run two large (~500 international recipients) lists on a DECstation
5000/240 running Ultrix 4.3. The lists are managed by Majordomo, but
sent out through a resender that maintains a database of message-ID's
(to prevent looping problems), filters out subscribe/unsubscribe
requests, etc. I'm invoking sendmail with the options "-odb -oep -oi".
Everything works fine, but I'm wondering if there's any way to improve
the turnaround time. The delay, according to syslog, ranges up to 3
hours for successful delivery on the first attempt. Monitoring the
sending process using top, I see that there's frequently idle CPU
time, so it's not CPU bound.
What, if anything, can I do to speed this up? Would sorting the list
by hostname help? (I think not, since it only takes sendmail a few
minutes to start sending messages out.) How about splitting up the
list and invoking sendmail individually on the pieces? Any other
