Most of the ISP's have a web mail interface for remote users, and most
companies have some form of remote web mail also. I have configured many
remote connections using a VPN solution to the company network for email
and file access.

Most hotels don't offer SMTP services, and most ISP's don't want people
outside their networks accessing their SMTP servers to SEND. With some
business accounts you can purchase a plan that permits the sender to
"authenticate" with the ISP's mail server no matter where they roam to.

If you need remote email, consider getting a mail provider that gives
you the access you need. Don't blame the residential ISP providers, they
are doing what they need to do in order to stay off block lists and to
fight relaying.
