We have 400+ user accounts on our virtualmin server. We also have tons of automated emails for all users which now takes tons of space. I want to remove all emails sent from “x@y.com” for all users with a single command. Is the command below enough or gonna work?

Thanks

sudo doveadm expunge -A mailbox INBOX from "x@y.com"

By the docs I can’t see the from option. Or is that a query search argument?

I quess there is only way to find out, maybe a test environment.
