- I haven't any experience with sendmail as I only use smail v2.5 but
- nevertheless here's something that might give you some ideas.
-
- Last August I set up a second machine as a news server so incoming
- news would be unpacked and put in the new spool on another machine,
- leaving the gateway machine (which people log onto) running at a
- more constant speed. This worked well except that if somebody posted
- a new article while news was being unpacked they had to wait as
- inews on the second machine got bogged down. Ralph Sims
- <ralphs@halycyon.com> sent me a trick version of mini-inews that
- didn't just send across the network to the real inews on the server,
- but put the article to be posted in a 'printer queue' and then
- returned to the user. The code is quite small (8K) and I could post
- it here if you/anybody was interested.
-
- Perhaps you could use something similar to queue the requests to
- sendmail.
-
- Hope that helps,
-
- Dave
