The publically available Exim users mailing list archives show a lot more. For example: "... we use an old SparcStation 20 to ship around 60,000 emails a day and according to the exim stats 98% of those are shipped in under a minute. The load average on the machine is next to nothing to the extent that I get paranoid if it ever approaches one." (<20000714095714.E17070@apple.ukc.ac.uk>) "... My server processes 50,000 to 100,000 messages a day and every one of those passes through a filter that currently contains 200 rules, mostly regex matches (checks for worms and viruses, scores potential spam, etc.) Server load hovers around 0.30 (FreeBSD, Pentium III 400MHz) with the odd "spike" to 1.0 or so." () "Under exim, I put about 5GB (bytes not bits) from one machine between 8pm and 9am. That is over one million outbound emails in 12 hours. You do the math. That is a lot of traffic and is on a small dual processor PIII with a single SCSI disk (no stripe for the spool). ..." (<396C78B5.4D54B104@cnds.jhu.edu>) (The same admin also says:) "... We deliver about 1.5 million message/day on any given machine. But, we don't push mail between 11am and 8pm (only 8pm to 11am)." There are many other documented. Someone should make a "DJB's slander (his word) against ..." Jeremy C.
