I manage a number of email addresses on a daily basis. Some of the servers have great spam checking filters while others get legitimate emails caught in the filters by mistake on a regular basis. Regardless of the filters I setup or whitelist and blacklists I edit and update, I find myself scanning my junk mail folder for some services at least weekly.
I will regularly sort my Junk Mail folders by "Subject" which for me makes it very easy to scan through subject lines that are usually very similar and the only difference is the spoofed email address they’ve created from the "From" line.
It can depend on your personal preference, sorting by "From" can also be helpful sometimes, especially if you’re looking for a specific address that always seems to get a false positive identification as spam.
Both of these options work far better for me than the default sorting method of "Date".
