I get throttling and I don't understand how, why and where to control or configure, I get bounces because of x-powermta all resources disabled,
and I don't want to learn powerMTA. I'd rather learn postfix
Have you read a bit on the postfix site? There are also postfix admin tools at github, just search a bit and check them out
yes I have been reading a lot on postfix site and a lot of tutorials too but as I said I didn't find the last step. Basically tutorials stop when you have tested postfix from command line. What I cannot figure out is how to connect it to mailwizz. So I thought someone might give me a pointer on that. Sure there are people here who use postfix.
But I will take your hint and read again, maybe I missed something there
What makes you think that? After all, you got actually useful answers!
Well if I search for help how to connect postfix and mw then "you should/MUST use third party SMTP" is not a helpful answer, I think ..
I have tried 3rd party and they have either closed me down before I could send 1st email or they give me rotten deliverability,
like mailgun that cannot inbox aol at all just as an example. If I send an email and then have like 5000 bounces and aol-addresses all blacklisted because of that, it just means a lot of work un-blacklisting them again cause these are openers and I was sending them from my own smtp for month without problem.
Thus only saying, 3rd party smtp may not be the holy grail of email sending.
