How to configure gray lists (Postfix + Postgrey+Exchange) correctly?
I have a configured configuration from
Postfix - as an external MTA and an
Exchange spam cutter - as the final server for receiving letters
I screwed it to my Postfix - PostGrey - in order to cut off very impudent spam and noticed such nonsense that in the modern world a lot of companies use Office365 and other public mailers for
spammers keep up and start sending spam from outlook.com / google.com servers as well Postgrey
for some reason checks the sender's host, not the mail domain and as a result I have a carousel until this chain works and the letter will end up in the mailbox.
