Allow blocking of any domain name
I tried to block the domain of a spam email, 'pjmibh.org.uk' and got the error message "The domain to block is invalid". If it is invalid why wasn't it flagged as spam? Please spend my subscription fee on fixing spam filtering, not some exec's bonus.

Daniel, I have noticed some email addresses from a Sender where emoji or spaces are placed in the address which if copied/pasted in the filter or block list the invalid message comes up because the emoji or space can not be read as a viable character in the address. You have to remove the emoji/blank space to list the address correctly. Hope that helps!
