> We have found that the USPS is under attack from text scams

The core challenge of phishing attacks is that USPS is not, in fact, the primary victim of these attacks.

The victims are distributed citizens who fall for the scam. USPS doesn't have very many levers available to them to address the attacks (besides a warning on their site, which they have), but also doesn't 'feel' the impact so would have a hard time justifying substantial investment in addressing it.

Ultimately the solution needs to come from regulatory regimes that target fraud, particularly SMS message spam.

The USPS is empowered with a law enforcement branch to defend against attacks on the mail system.

The problem is usually that domestic law enforcement is powerless against international crime, which gets laundered by international utilities like DNA and IP routing/peering.
