As a comparison, we have Listserv hand off to a local Sendmail that then does delivery to destination mail servers. Best I ever managed for a single large posting was a 75K recipient posting handed off to Sendmail, enqueued on the local Sendmail queue in about 5 minutes, and 75% delivered to remote destinations in 15 minutes. But let's just say that Sendmail config was just a tad more tuned for outbound delivery than what your standard Linux distro installs. It's *hard* to get Sendmail to accept 250+ RCPT TO's per second - in particular, you need to either avoid letting Sendmail issue any DNS lookup during the accept phase, or run a local DNS cache and hope for a 100% hit rate, or both :) ############################ To unsubscribe from the LSTSRV-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTSRV-L&A=1
