right tool for creating an 'accurate' test email from an external domain?

[PGNet Dev]

I'm troubleshooting an annoyingly problematic single-sender's rejections.

With my usual simple monkeying with smtpd_mumble_restrictions, per-milter whitelisting, etc. I haven't yet found all the problems.

For testing, I'd *like* to 'accurately' spoof an email from sender's IP/helo/from/to -- without having my hands on a received email -- to (re)inject into my postfix et al chain.

Ideally, into the postscreen front-end. Or, at least, as early as possible ...

To date, I've really only ever made sure to _avoid_ spoofing, etc, and validated with real/legit senders.

What's the right tool/method for the job?  Specifically, for synthesizing a 'faux legit' email?
