You are over-crediting that functionality.

A webmail provider that proxies images may "protect" you from the sender 
discovering your IP address (a trivial piece of information that in most 
cases isn't worth collecting) but you cannot depend on that. It DOES NOT 
protect you from email address verification and in some cases has been 
intentionally designed to avoid disrupting "open tracking" by senders. 
It's an anti-malware and UI tactic, not part of a privacy strategy.
