Just a comment. I received the following while trying to add a non-standard domain name to the sender filter,
Error: There were problems with one or more entries.
Illegal value (.loan) for New Email Address/Domain:must be a top-level domain like 'edu' or domain like 'yourdomain.com' or email address like 'email@example.com'.
Now, I can understand why I would get this, however, spammers aren't playing by the rules so why should we have to be limited in this particular area. I should be able to block a domain name of 'courtesy.uuggss.loan' which is used on the internet for spammers.
Please change the program so I can enter just about anything in the sender filters.
