Thunderbird - Reduce phishing by blocking links from strangers

[Mutzu]

The following would be a simple but effective measure to reduce successful phishing attempts by 95% (I guess 😀) :

Do not allow a link to be opened from an email whose sender address is not stored in the address book or in a whitelist maintained by the user.

Actually, I think, this should be the the default behavior of Thunderbird that could be changed.
