Question about catch all and bounce

[schmidtedv]

I'm thinking about how it works...

I use the email name@firma.de and put in some aliases, lets say fritz/heinz/karl.

First, for ISPConfig, is it correct then, that name@firma.de will collect fritz@firma.de ...too?

Second, if I don't use catch all for this account but this is my only mailadress for the domain firma.de...would other mails like franz@firma.de automatically get bounced or would they stay somewhere until there is an catch all account that collects them?

Third, would it then be enough to put an anti-spam config like the following into main.cf to get rid of unused mails?

Yes, they'd get bounced.
