Dear Postfix community, I'm developing a new milter and I need to benchmark it when plugged into Postfix. What are my best options for generating an SMTP stream of messages directed at a single Postfix instance at rates on the order of hundreds per second, and measuring SMTP acceptance rates and SMTP response latency? I can run processes on multiple machines if necessary, but the more efficient the better.
I saw the smtp-source tool <http://www.postfix.org/smtp-source.1.html>, but I'm not sure I can tune it to certain output rates and make it take acceptance rate and latency measurements. Are there any other tools people use to benchmark their Postfix setups or, more specifically, milters? Thanks, -Julian
