Re: handling spam from gmail.

• Hendrik Boom:

I use greylisting with my postfix. On Debian and Devuan th package is called 'postgrey'.

Classical, time-based greylisting like Postgrey is problematic in this age of 2FA and other email-based confirmation codes. Besides, Postfix has its own, superior mechanism called "Postscreen" built in.

This has recently been discussed once again, in-depth, on the Postfix mailing list, so I suggest interested parties to check the ML archives.
