Thanks for the infos. Ideally, I was looking for a simple Windows app
as MTA, but a Python script is OK.

I'm not sure my ISP blocks outbound port 25 connections. I'll
experiment with a small Linux box.

I wist they would use a smarter SPAM filter that wouldn't flag
perfectly legit-looking outgoing e-mails.
