No. sendmail is an MTA, not a performance testing tool... There are different "load generators" available: Netscape has something (I forgot the name), postal is a test program (which I never got to compile), and smtp-source/smtp-sink from postfix. I have also written some load generators, but they require a specific environment. > (2) Is each mail stored in its own file? The format of the sendmail mail queue is documented in doc/op/op.* (should be in /usr/share/doc/smm/08.sendmailop on FreeBSD). In brief: it uses two files: data (message body) and envelope / headers / some other routing data.
