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 (john@smith.com), I'm likely to get spam from john@smith.com; but the sender's name will not be John Smith, but some other name picked at random by the spammer; e.g., "Joe Average <john@smith.com>".

Currently, when getting such a message, it bypasses the junk filter because john@smith.com is in my address book, and I've picked "always trust mail from known sender". But in my address book, john@smith.com 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.

Reproducible: Always

Steps to Reproduce:
N/A
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 <john@smith.com>" decides to change his displayed name to "J. Smith <john@smith.com>", 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.

Severity: normal → S3
