[plug] mail server performance

[Omar Cromwell Mercado]

sendmail performance has been my concern lately. Our company maintains a linux box dedicated solely for mailing lists which sends around 400,000 mails per day (at two 200K batches)..  It's quite a good machine (dual-p3, 128mb) sitting on a 192k asymmetric dsl with no other significant traffic other than mails. The lists are generally non-interactive.. Our list manager is "Subscribe Me" provided by cgiscriptcenter.com. The problem is it takes about 40 hours to complete the two batches!   We may need to replace the list manager with listserv, listar, majordomo or others but isnt it the mail server (sendmail) that holds the greatest performance factor? I'd appreciate if you could give hints and tips to make delivery faster under sendmail.   lsmtp of l-soft claims to be the fastest (but it's only for nt and openvms, so it would be a hard choice when i have to  administer remotely, though i know co. management will ultimately consider it). Any thoughts on this claim?     Best regards.   _____________________________________________________                                                  Omar Cromwell A.
