Outgoing Spam Quarantine

that should work already, you have to activate a rule that quarantines spam on outgoing mails
 
what do you mean by that?

my friend there are 100+ incoming spam
and 500+ outgoing spam on my quarantine.

How can i remove all outgoing spams at one time? Ineed to filter them first and delete ?
Is here any way for this ?

If you ask me outgoing spam quarantine can be totaly separate from the incoming
 
and 500+ outgoing spam on my quarantine.

How can i remove all outgoing spams at one time? Ineed to filter them first and delete ?
Is here any way for this ?

first i would try to see where the outgoing spam comes from and solve it at the source

also you can select all spam (per target) by clicking the square on the top left of the grid

also there is always the possiblity of scripting via the api/cli
see the pmg api documentation https://pmg.proxmox.com/pmg-docs/api-viewer/index.html
you can use that with any http client (e.g. curl) or via the builtin tool: 'pmgsh'
