Hi, I have an urgent problem relating to the communication between listserv en our sendmail V8.6.12. The problem is that when we send one mailing to a list of about 5000 subscribtions our sendmail forks of so many processes that our 4 CPU sparc 1000E goes crazy and pushes the load to record hights of 40 or higher. We eliminated the problem to be in - lack of a precedence header in the list submission - configuration tuning of sendmail itself. Question: - Does anyone uses this combination of listserv and sendmail V8.6.12 for delivery with big lists. If yes do you have problems and how did you tune it - Can listserv insert a 'Precedence: bulk' header in all submissions? If yes how? - Does anyone have any ideas on how to solve our problem.
