There's a 2B: lash out $15 on a Maglobe account. That's $15 of credit for using their dial-up access when out and about, but it also includes an authenticating SMTP server. Regardless of how you connected to the internet, you send your mail via the Maglobe SMTP facility. I've been doing it for years.
Maglobe is also just about the cheapest option when in those US hotels that don't offer free WiFi and charge for calls to an ISP. There's a 1-800 contact number - you pay, but it's something like $4 an hour in the USA.
