Easy with Office 365/Exchange Online. You configure the domain's MX records to point to Microsoft, and then on Microsoft's control panel you buy mailboxes per human being.
Then you assign addresses to the mailboxes, e.g. email@example.com and firstname.lastname@example.org and email@example.com goes to mailbox1. Anything not listed is rejected at the SMTP level, so no email flows.
If you accept everything *@domain.dom then you have to filter once you receive. This is wasteful as spam emails are getting larger and larger (in some cases tens of megabytes).
Many anti-spam researchers say there is no point in this, it just adds complexity for you. I can't find the research right now.
That isn't what I meant,what I was meanining was if you say signed up with plusnet for example and they issued with or you chose an email address or a few email addresses and some of those got compromised how easy would be for you or I to get a company like Plusnet like plusnet to completely disable those email addresses,what obligation do they have to do so?In fact would that make any difference to the ability of the hacker sending emails pretending to be you or I?
I don't worry about spam I just rely on mailwasher to get rid of the [censored] I don't want before it gets to my pc
