I know Xeams has a TLD blacklist.  Would it be possible to introduce a TLD whitelist that functions similarly to Country Filters?  That is to say we could invert the list and introduce a score to any TLD that is not on the list.

I'm new to Xeams and wasn't sure of the proper place to request a feature.  If this isn't it I'm happy to resubmit elsewhere.

Bobby,

Presumably, the list for whitelisted TLDs will be much smaller than the blacklisted ones. Therefore, you can accomplish this task by adding a sender filter and specifying a country's top-level domain. Consider the following example showing whitelisting Switzerland.

Correct, the whitelist would be maybe 10 or less TLDs and certainly shorter than the blacklist would have to be.  This could work.  Doing it this way I think I'd need a high score on every message then follow-up with a negative score for each TLD on my whitelist.  Having a dedicated list would be somewhat more intuitive so I'd still request the feature at some point in the future.
