Presumably you don't send out emails appearing to come from service@paypal.com saying things like "Reminder: You've still got a money request", with an HTML body that looks exactly like Paypal but contains a fraudulent link and phone number, so you should be fine.
No, I didn't. I did get those emails a lot on my university dot edu email. I understand there are legacy/compatibility challenges with the telephone infrastructure but you'd think this problem is entirely solvable with emails. :/
