Spammers often try to correlate email addresses (e.g., found on same web page). If they correlate my email with that of my friend John Smith ([e-mail]), I'm likely to get spam from [e-mail]; but the sender's name will not be John Smith, but some other name picked at random by the spammer; e.g., "Joe Average <[e-mail]>".

Currently, when getting such a message, it bypasses the junk filter because [e-mail] is in my address book, and I've picked "always trust mail from known sender". But in my address book, [e-mail] is listed as "John Smith", *not* as "Joe Average". Such mismatches are easy to find, and either flag as spam or at least pass through the spam filter even if the email is in my address book.

I often get mail with "wrong" (but correct) name
 - all lowercase
 - firstname lastname - lastname firstname switched
 - including company name

So at least those should be considered if this is implemented

I would vote against this one. The displayed name is a setting any user can change trivially, and many do. So if my friend John Smith, who normally displays his address as "John Smith <[e-mail]>" decides to change his displayed name to "J. Smith <[e-mail]>", or does so accidentally when switching to a new email client, then from that day onwards all his mail would end up in my junk folder!

Against.
For at least two years there has been a huge problem with mails going to spam even if in the address book, even if marked as desired/wanted dozens times. To no avail.
Adding next chance to get emails from clients and coops to spam folder is not what I would want, sorry.
