wow, is most of that email junk?
Does he use the Verizon webmail ?

He can set up or turn on the junk filter and that would stop a lot of it from getting thru to the inbox.
It is a good idea to block the junk mail so it doesn't even get to your inbox - some of it can contain unsafe attachments or other bad stuff- just by opening it or taking a quick look it can set it in motion.

Verizon info-
[Junk Mail

You can set your Junk filtering options to perfrom the following operations in incoming mail that has already been identified as junk:

* Delete incoming Junk Mail goes straight to your Trash folder
* Save Junk in the Junk folder
* Disable Junk filtering Junk will appear in your Inbox just like regular mail

Blocked Senders

If you do not want to receive mail from a particular person, add their email address to this list. If you do not want to receive email from an entire company, add their domain name (eg. badspammer.com) to this list. To accept email from that person or company again, just remove their address from this list by clicking Unblock.

Mail from these domains/addresses is placed in your Junk folder, unless the sender is on your allow list. As an example, a you can set up a block list that includes address.com. This would ordinarily result in all mail from the address.com domain being put in your Junk folder. However, if the you also have the address michael@address.com in your allow list, and an email from that address is received, it will arrive in your inbox. ]
