Sendmail performance tuning

[tharawit]

I need to blast e-mail to thousands of customers everyday. The problem is, when sendmail is blasting e-mails, it consumes all the resource. So,we cannot send any e-mail out during that time. Anyone have an idea how to fix this? Thank you.

If you're overloading the server, then you're overloading the server and there is nothing you can do about it. Buy another server and use one for the sending process, leaving the other one for your normal company email.
