Topic: Whitelist incoming email addresses
I'm considering setting up a iRedMail server using a whitelist to restrict incoming email.
eg: firstname.lastname@example.org (on my iRedMail server) has a whitelist of (allowed) emails: 'email@example.com,firstname.lastname@example.org'
The requirement is any email not in that list will get returned to sender as not received,
so in above example only email@example.com and firstname.lastname@example.org would be able to send email to email@example.com (which is using iRedMail), any other email addresses would be rejected.
Assuming this is possible, can I set up individual whitelists for each users email address (on my iRedMail server) and is this data stored in a table that I as administrator of iRedMail can access/edit etc?
Could you confirm that this can be done?
