The latter numbers (127.0.0.1 @6.0MBytes/s) are *considerably* better than those occurring with the test attachment I was using (http://sigmasys.co.uk/postfix/test.bin), where a 2Mb attachment via SMTP takes well over a minute to be processed. I'm not sure why this might be, or why I obtain results more comparable to 6.0MBytes/s when mail arrives via pickup. As far as I can tell cleanup goes through the same process each time independent of how mail is presented to it. -- Dave Green
