Blacklisted Email / domain

What happens to the emails if marked as blacklisted mail / domain, is it just deleted from eMclient / pop3 server. Is it possible to remove an email / domain from blacklist, if i add an email / domain by mistake to blacklist.

I generally set eMclient to read incoming mails as Text. Is it possible to view, if required, single / individual mail in HTML format?

You can go to “rules” and then see the blacklist rule. There you will be able to modify the emails or domains as well as remove them from the blacklist.
