To find out if Postfix works, send mail into Postfix and see if it
delivers the message within a set time.
For example:
- Submit over SMTP, perhaps with a "mini SMTP client".
- Submit with Postfix sendmail command.
- Deliver mail over SMTP, perhaps over a dedicated server and port.
- Deliver mail locally, perhaps via a pipe-to-command.
Other performance metrics would be the size of the queues.
