I use postfix, and I've certainly had up to 30.000 emails queued without any slow downs. It sounds like maybe you are back to what someone suggested - due to the many emails (which is very suspect) you're delivering over SMTP, your connection is being tarpitted or otherwise artificially slowed down. What I don't understand is how the same can apply if you just use /usr/sbin/sendmail to deliver them. That way they should just go straight in the queue and nothing should be able to slow down that process - it's just writing a file to disk after all. I would go back to using sendmail (instead of SMTP), and when the slowdown begins, I would attach an strace to see what's really going on. /Per Jessen, Zürich
