Len - Thanks for your response. According to the IMAIL manual, you are supposed to divide the total number of recipients by 25 and enter that in as the "messages per process."
Our list is 150,000 addresses so won't 6000 messages per process basically put the server on it's knees? We're going to upgrade the SMTP server but would like to continue using Windows & Imail for this job. There must be a more concrete way to establish the requirements (hardware/software specifications) for sending to a list of this size? I'm assuming there are folks out there who use IMAIL successfully to send to 150,000+ lists? ---------- Original Message ---------------------------------- From: Len Conrad <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] Date: Tue, 11 Mar 2003 22:14:36 -0600 > >>We're running a 233mhz mail server with 128mg of RAM. >> >>Any ideas on the maximum size list that can be supported in this size >>server? > >What size of list(s) do you have in mind? > >Looking at it from another POV, no matter what the size of machine is, >Imail has a spotty record of delivering lists.
