Some weeks ago I set up a MailGun account to forward all mail directed to addresses under my domain to my private Gmail (like a catch-all-address). I received ~5 spam mails per day, to addresses I never used before.Some days ago I switched to G Suite as my mail provider and set up a catch all address again. Now I do not receive a single spam mail anymore (neither Inbox nor Spam), but my catch-all-setup is working.In the past, when I just used private Gmail, I noticed receiving significantly less junk-mail than on other accounts at i.e. German Telekom, even though I use my Gmail account at way more places.Does Google (specifically G Suite Gmail) block or delete mails, when it's very sure they are spam? If yes how can Google be sure to just block real spam? Do they send bounce mails?Does Google block or delete spam just when received via a catch-all-address?
Does G Suite spam filtering automatically delete?
